DESCRIPTION
|
2009-07-03 20:03:25 +08:00
|
|
|
<<mktemp>>, <<mkstemp>>, and <<mkstemps>> attempt to generate a file name
|
|
|
|
that is not yet in use for any existing file. <<mkstemp>> and <<mkstemps>>
|
|
|
|
create the file and open it for reading and writing; <<mktemp>> simply
|
2010-07-20 02:21:11 +08:00
|
|
|
generates the file name (making <<mktemp>> a security risk). <<mkostemp>>
|
|
|
|
and <<mkostemps>> allow the addition of other <<open>> flags, such
|
|
|
|
as <<O_CLOEXEC>>, <<O_APPEND>>, or <<O_SYNC>>. On platforms with a
|
|
|
|
separate text mode, <<mkstemp>> forces <<O_BINARY>>, while <<mkostemp>>
|
|
|
|
allows the choice between <<O_BINARY>>, <<O_TEXT>>, or 0 for default.
|
|
|
|
<<mkdtemp>> attempts to create a directory instead of a file, with a
|
|
|
|
permissions mask of 0700.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
|
|
|
You supply a simple pattern for the generated file name, as the string
|
|
|
|
at <[path]>. The pattern should be a valid filename (including path
|
2009-07-03 20:03:25 +08:00
|
|
|
information if you wish) ending with at least six `<<X>>'
|
2000-02-18 03:39:52 +08:00
|
|
|
characters. The generated filename will match the leading part of the
|
|
|
|
name you supply, with the trailing `<<X>>' characters replaced by some
|
2009-07-03 20:03:25 +08:00
|
|
|
combination of digits and letters. With <<mkstemps>>, the `<<X>>'
|
|
|
|
characters end <[suffixlen]> bytes before the end of the string.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
2009-07-03 20:03:25 +08:00
|
|
|
The alternate functions <<_mktemp_r>>, <<_mkdtemp_r>>, <<_mkstemp_r>>,
|
2010-07-20 02:21:11 +08:00
|
|
|
<<_mkostemp_r>>, <<_mkostemps_r>>, and <<_mkstemps_r>> are reentrant
|
|
|
|
versions. The extra argument <[reent]> is a pointer to a reentrancy
|
|
|
|
structure.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
|
|
|
RETURNS
|
|
|
|
<<mktemp>> returns the pointer <[path]> to the modified string
|
|
|
|
representing an unused filename, unless it could not generate one, or
|
|
|
|
the pattern you provided is not suitable for a filename; in that case,
|
2010-07-20 02:21:11 +08:00
|
|
|
it returns <<NULL>>. Be aware that there is an inherent race between
|
|
|
|
generating the name and attempting to create a file by that name;
|
|
|
|
you are advised to use <<O_EXCL|O_CREAT>>.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
2009-07-03 20:03:25 +08:00
|
|
|
<<mkdtemp>> returns the pointer <[path]> to the modified string if the
|
|
|
|
directory was created, otherwise it returns <<NULL>>.
|
|
|
|
|
2010-07-20 02:21:11 +08:00
|
|
|
<<mkstemp>>, <<mkstemps>>, <<mkostemp>>, and <<mkostemps>> return a file
|
|
|
|
descriptor to the newly created file, unless it could not generate an
|
|
|
|
unused filename, or the pattern you provided is not suitable for a
|
|
|
|
filename; in that case, it returns <<-1>>.
|

|
|
|
|
2009-03-14 20:14:08 +08:00
|
|
|
NOTES
|
|
|
|
Never use <<mktemp>>. The generated filenames are easy to guess and
|
|
|
|
there's a race between the test if the file exists and the creation
|
|
|
|
of the file. In combination this makes <<mktemp>> prone to attacks
|
|
|
|
and using it is a security risk. Whenever possible use <<mkstemp>>
|
|
|
|
instead. It doesn't suffer the race condition.
|
|
|
|
|
2000-02-18 03:39:52 +08:00
|
|
|
PORTABILITY
|
|
|
|
ANSI C does not require either <<mktemp>> or <<mkstemp>>; the System
|
2009-07-03 20:03:25 +08:00
|
|
|
V Interface Definition requires <<mktemp>> as of Issue 2. POSIX 2001
|
2010-07-20 02:21:11 +08:00
|
|
|
requires <<mkstemp>>, and POSIX 2008 requires <<mkdtemp>> while
|
|
|
|
deprecating <<mktemp>>. <<mkstemps>>, <<mkostemp>>, and <<mkostemps>>
|
|
|
|
are not standardized.
|
2000-02-18 03:39:52 +08:00
|
|
|
|
2009-07-03 20:03:25 +08:00
|
|
|
Supporting OS subroutines required: <<getpid>>, <<mkdir>>, <<open>>, <<stat>>.
