MALLOC_STATS(3) Linux Programmer's Manual MALLOC_STATS(3)

NAME

     malloc_stats - print memory allocation statistics

SYNOPSIS

     #include <malloc.h>
     void malloc_stats(void);

DESCRIPTION

     The malloc_stats() function prints (on standard error) statistics about
     memory allocated by malloc(3) and related functions.   For  each  arena
     (allocation  area),  this  function  prints  the total amount of memory
     allocated and the total number of bytes consumed by in-use allocations.
     (These two values correspond to the arena and uordblks fields retrieved
     by mallinfo(3).)  In addition, the function prints the sum of these two
     statistics  for  all arenas, and the maximum number of blocks and bytes
     that were ever simultaneously allocated using mmap(2).
