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).
