SYNOPSIS
2000-02-18 03:39:52 +08:00
#include <malloc.h>
struct mallinfo mallinfo(void);
void malloc_stats(void);
int mallopt(int <[parameter]>, <[value]>);
struct mallinfo _mallinfo_r(void *<[reent]>);
void _malloc_stats_r(void *<[reent]>);
int _mallopt_r(void *<[reent]>, int <[parameter]>, <[value]>);
DESCRIPTION
<<mallinfo>> returns a structure describing the current state of
memory allocation. The structure is defined in malloc.h. The
following fields are defined: <<arena>> is the total amount of space
in the heap; <<ordblks>> is the number of chunks which are not in use;
<<uordblks>> is the total amount of space allocated by <<malloc>>;
<<fordblks>> is the total amount of space not in use; <<keepcost>> is
the size of the top most memory block.
<<malloc_stats>> print some statistics about memory allocation on
standard error.
<<mallopt>> takes a parameter and a value. The parameters are defined
in malloc.h, and may be one of the following: <<M_TRIM_THRESHOLD>>
sets the maximum amount of unused space in the top most block before
releasing it back to the system in <<free>> (the space is released by
calling <<_sbrk_r>> with a negative argument); <<M_TOP_PAD>> is the
amount of padding to allocate whenever <<_sbrk_r>> is called to
allocate more space.
The alternate functions <<_mallinfo_r>>, <<_malloc_stats_r>>, and
<<_mallopt_r>> are reentrant versions. The extra argument <[reent]>
is a pointer to a reentrancy structure.
RETURNS
<<mallinfo>> returns a mallinfo structure. The structure is defined
in malloc.h.
<<malloc_stats>> does not return a result.
<<mallopt>> returns zero if the parameter could not be set, or
non-zero if it could be set.
PORTABILITY
<<mallinfo>> and <<mallopt>> are provided by SVR4, but <<mallopt>>
takes different parameters on different systems. <<malloc_stats>> is
not portable.
