| .TH MALLOC_STATS 3 2015-07-23 "Linux" "Linux Programmer's Manual" |
| .SH NAME |
| malloc_stats \- print memory allocation statistics |
| .SH SYNOPSIS |
| .B #include <malloc.h> |
| |
| .B void malloc_stats(void); |
| .SH DESCRIPTION |
| The |
| .BR malloc_stats () |
| function prints (on standard error) statistics about memory allocated by |
| .BR 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 |
| .I arena |
| and |
| .I uordblks |
| fields retrieved by |
| .BR 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 |
| .BR mmap (2). |
| .\" .SH VERSIONS |
| .\" Available already in glibc 2.0, possibly earlier |
| .SH ATTRIBUTES |
