malloc_stats(3) Library Functions Manual malloc_stats(3)
NAME
malloc_stats - print memory allocation statistics
LIBRARY
Standard C library (libc, -lc)
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 al-
located 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).
