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. - -*/ - -#include <_ansi.h> -#include <reent.h> -#include <stdlib.h> -#include <malloc.h> -#include <stdio.h> - -#ifndef _REENT_ONLY - -struct mallinfo -_DEFUN_VOID (mallinfo) -{ - return _mallinfo_r (_REENT); -} - -void -_DEFUN_VOID (malloc_stats) -{ - _malloc_stats_r (_REENT); -} - -int -_DEFUN (mallopt, (p, v), - int p _AND - int v) -{ - return _mallopt_r (_REENT, p, v); -} - -#endif - -/* mstats is now compatibility code.
