+ * This file defines four types of data structures: singly-linked lists,
+ * singly-linked tail queues, lists and tail queues.
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A singly-linked tail queue is headed by a pair of pointers, one to the
+ * head of the list and the other to the tail of the list. The elements are
+ * singly linked for minimum space and pointer manipulation overhead at the
+ * expense of O(n) removal for arbitrary elements. New elements can be added
+ * to the list after an existing element, at the head of the list, or at the
+ * end of the list. Elements being removed from the head of the tail queue
+ * should use the explicit macro for this purpose for optimum efficiency.
+ * A singly-linked tail queue may only be traversed in the forward direction.
+ * Singly-linked tail queues are ideal for applications with large datasets
+ * and few or no removals or for implementing a FIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+
+INDEX
+	bsearch
+
+ANSI_SYNOPSIS
+	#include <stdlib.h>
+	void *bsearch(const void *<[key]>, const void *<[base]>,
+		size_t <[nmemb]>, size_t <[size]>,
+		int (*<[compar]>)(const void *, const void *));
+
+TRAD_SYNOPSIS
+	#include <stdlib.h>
+	char *bsearch(<[key]>, <[base]>, <[nmemb]>, <[size]>, <[compar]>)
+	char *<[key]>;
+	char *<[base]>;
+	size_t <[nmemb]>, <[size]>;
+	int (*<[compar]>)();
+
+DESCRIPTION
+<<bsearch>> searches an array beginning at <[base]> for any element
+that matches <[key]>, using binary search.  <[nmemb]> is the element
+count of the array; <[size]> is the size of each element.
+
+The array must be sorted in ascending order with respect to the
+comparison function <[compar]> (which you supply as the last argument of
+<<bsearch>>).
+
+You must define the comparison function <<(*<[compar]>)>> to have two
+arguments; its result must be negative if the first argument is
+less than the second, zero if the two arguments match, and
+positive if the first argument is greater than the second (where
+``less than'' and ``greater than'' refer to whatever arbitrary
+ordering is appropriate).
+
+RETURNS
+Returns a pointer to an element of <[array]> that matches <[key]>.  If
+more than one matching element is available, the result may point to
+any of them.
+
+PORTABILITY
+<<bsearch>> is ANSI.
+
+No supporting OS subroutines are required.

+ *		    OVERFLOW_PAGE_NUMBER OVFLPAGE
+ *
+ * PARTIAL_KEY	This must be the first key/data pair on a page
+ *		and implies that page contains only a partial key.
+ *		That is, the key is too big to fit on a single page
+ *		so it starts on this page and continues on the next.
+ *		The format of the page is:
+ *		    KEY_OFF PARTIAL_KEY OVFL_PAGENO OVFLPAGE
+ *
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    PARTIAL_KEY -- 1
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ * FULL_KEY	This must be the first key/data pair on the page.  It
+ *		is used in two cases.
+ *
+ *		Case 1:
+ *		    There is a complete key on the page but no data
+ *		    (because it wouldn't fit).  The next page contains
+ *		    the data.
+ *
+ *		    Page format it:
+ *		    KEY_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    FULL_KEY -- 2
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ *		Case 2:
+ *		    This page contains no key, but part of a large
+ *		    data field, which is continued on the next page.
+ *
+ *		    Page format it:
+ *		    DATA_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *		    KEY_OFF -- offset of the beginning of the data on
+ *				this page
+ *		    FULL_KEY -- 2
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ * FULL_KEY_DATA
+ *		This must be the first key/data pair on the page.
+ *		There are two cases:
+ *
+ *		Case 1:
+ *		    This page contains a key and the beginning of the
+ *		    data field, but the data field is continued on the
+ *		    next page.
+ *
+ *		    Page format is:
+ *		    KEY_OFF FULL_KEY_DATA OVFL_PAGENO DATA_OFF
+ *
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    FULL_KEY_DATA -- 3
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    DATA_OFF -- offset of the beginning of the data
+ *
+ *		Case 2:
+ *		    This page contains the last page of a big data pair.
+ *		    There is no key, only the  tail end of the data
+ *		    on this page.
+ *
+ *		    Page format is:
+ *		    DATA_OFF FULL_KEY_DATA <OVFL_PAGENO> <OVFLPAGE>
+ *
+ *		    DATA_OFF -- offset of the beginning of the data on
+ *				this page
+ *		    FULL_KEY_DATA -- 3
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ *		    OVFL_PAGENO and OVFLPAGE are optional (they are
+ *		    not present if there is no next page).

+.Lb libc
+.Sh SYNOPSIS
+.In search.h
+.Ft int
+.Fn hcreate "size_t nel"
+.Ft void
+.Fn hdestroy void
+.Ft ENTRY *
+.Fn hsearch "ENTRY item" "ACTION action"
+.Sh DESCRIPTION
+The
+.Fn hcreate ,
+.Fn hdestroy ,
+and
+.Fn hsearch
+functions manage hash search tables.
+.Pp
+The
+.Fn hcreate
+function allocates sufficient space for the table, and the application should
+ensure it is called before
+.Fn hsearch
+is used.
+The
+.Fa nel
+argument is an estimate of the maximum
+number of entries that the table should contain.
+This number may be adjusted upward by the
+algorithm in order to obtain certain mathematically favorable circumstances.
+.Pp
+The
+.Fn hdestroy
+function disposes of the search table, and may be followed by another call to
+.Fn hcreate .
+After the call to
+.Fn hdestroy ,
+the data can no longer be considered accessible.
+.Pp
+The
+.Fn hsearch
+function is a hash-table search routine.
+It returns a pointer into a hash table
+indicating the location at which an entry can be found.
+The
+.Fa item
+argument is a structure of type
+.Vt ENTRY
+(defined in the
+.Aq Pa search.h
+header) containing two pointers:
+.Fa item.key
+points to the comparison key (a
+.Vt "char *" ) ,
+and
+.Fa item.data
+(a
+.Vt "void *" )
+points to any other data to be associated with
+that key.
+The comparison function used by
+.Fn hsearch
+is
+.Xr strcmp 3 .
+The
+.Fa action
+argument is a
+member of an enumeration type
+.Vt ACTION
+indicating the disposition of the entry if it cannot be
+found in the table.
+.Dv ENTER
+indicates that the
+.Fa item
+should be inserted in the table at an
+appropriate point.
+.Dv FIND
+indicates that no entry should be made.
+Unsuccessful resolution is
+indicated by the return of a
+.Dv NULL
+pointer.
+.Sh RETURN VALUES
+The
+.Fn hcreate
+function returns 0 if it cannot allocate sufficient space for the table;
+otherwise, it returns non-zero.
+.Pp
+The
+.Fn hdestroy
+function does not return a value.
+.Pp
+The
+.Fn hsearch
+function returns a
+.Dv NULL
+pointer if either the
+.Fa action
+is
+.Dv FIND
+and the
+.Fa item
+could not be found or the
+.Fa action
+is
+.Dv ENTER
+and the table is full.
+.Sh ERRORS
+The
+.Fn hcreate
+and
+.Fn hsearch
+functions may fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+Insufficient storage space is available.
+.El
+.Sh EXAMPLES
+The following example reads in strings followed by two numbers
+and stores them in a hash table, discarding duplicates.
+It then reads in strings and finds the matching entry in the hash
+table and prints it out.

+FUNCTION
+<<qsort>>---sort an array
+
+INDEX
+	qsort
+
+ANSI_SYNOPSIS
+	#include <stdlib.h>
+	void qsort(void *<[base]>, size_t <[nmemb]>, size_t <[size]>,
+		   int (*<[compar]>)(const void *, const void *) );
+
+TRAD_SYNOPSIS
+	#include <stdlib.h>
+	qsort(<[base]>, <[nmemb]>, <[size]>, <[compar]> )
+	char *<[base]>;
+	size_t <[nmemb]>;
+	size_t <[size]>;
+	int (*<[compar]>)();
+
+DESCRIPTION
+<<qsort>> sorts an array (beginning at <[base]>) of <[nmemb]> objects.
+<[size]> describes the size of each element of the array.
+
+You must supply a pointer to a comparison function, using the argument
+shown as <[compar]>.  (This permits sorting objects of unknown
+properties.)  Define the comparison function to accept two arguments,
+each a pointer to an element of the array starting at <[base]>.  The
+result of <<(*<[compar]>)>> must be negative if the first argument is
+less than the second, zero if the two arguments match, and positive if
+the first argument is greater than the second (where ``less than'' and
+``greater than'' refer to whatever arbitrary ordering is appropriate).
+
+The array is sorted in place; that is, when <<qsort>> returns, the
+array elements beginning at <[base]> have been reordered.
+
+RETURNS
+<<qsort>> does not return a result.
+
+PORTABILITY
+<<qsort>> is required by ANSI (without specifying the sorting algorithm).

+.Sh NAME
+.Nm tsearch , tfind , tdelete , twalk
+.Nd manipulate binary search trees
+.Sh SYNOPSIS
+.In search.h
+.Ft void *
+.Fn tdelete "const void *key" "void **rootp" "int (*compar) (const void *, const void *)"
+.Ft void *
+.Fn tfind "const void *key" "void **rootp" "int (*compar) (const void *, const void *)"
+.Ft void *
+.Fn tsearch "const void *key" "void **rootp" "int (*compar) (const void *, const void *)"
+.Ft void
+.Fn twalk "const void *root" "void (*compar) (const void *, VISIT, int)"
+.Sh DESCRIPTION
+The
+.Fn tdelete ,
+.Fn tfind ,
+.Fn tsearch ,
+and
+.Fn twalk
+functions manage binary search trees based on algorithms T and D
+from Knuth (6.2.2).  The comparison function passed in by
+the user has the same style of return values as
+.Xr strcmp 3 .
+.Pp
+.Fn Tfind
+searches for the datum matched by the argument
+.Fa key
+in the binary tree rooted at
+.Fa rootp ,
+returning a pointer to the datum if it is found and NULL
+if it is not.
+.Pp
+.Fn Tsearch
+is identical to
+.Fn tfind
+except that if no match is found,
+.Fa key
+is inserted into the tree and a pointer to it is returned.  If
+.Fa rootp
+points to a NULL value a new binary search tree is created.
+.Pp
+.Fn Tdelete
+deletes a node from the specified binary search tree and returns
+a pointer to the parent of the node to be deleted.
+It takes the same arguments as
+.Fn tfind
+and
+.Fn tsearch .
+If the node to be deleted is the root of the binary search tree,
+.Fa rootp
+will be adjusted.
+.Pp
+.Fn Twalk
+walks the binary search tree rooted in
+.Fa root
+and calls the function
+.Fa action
+on each node.
+.Fa Action
+is called with three arguments: a pointer to the current node,
+a value from the enum
+.Sy "typedef enum { preorder, postorder, endorder, leaf } VISIT;"
+specifying the traversal type, and a node level (where level
+zero is the root of the tree).
+.Sh SEE ALSO
+.Xr bsearch 3 ,
+.Xr hsearch 3 ,
+.Xr lsearch 3
+.Sh RETURN VALUES
+The
+.Fn tsearch
+function returns NULL if allocation of a new node fails (usually
+due to a lack of free memory).
+.Pp
+.Fn Tfind ,
+.Fn tsearch ,
+and
+.Fn tdelete
+return NULL if
+.Fa rootp
+is NULL or the datum cannot be found.
+.Pp
+The
+.Fn twalk
+function returns no value.
