27 | .SH NAME |
28 | malloc_stats \- print memory allocation statistics | |
29 | .SH SYNOPSIS | |
30 | .B #include <malloc.h> | |
dbfe9c70 | 31 | .PP |
067568db MK |
32 | .B void malloc_stats(void); |
33 | .SH DESCRIPTION | |
34 | The | |
35 | .BR malloc_stats () | |
36 | function prints (on standard error) statistics about memory allocated by | |
37 | .BR malloc (3) | |
38 | and related functions. | |
39 | For each arena (allocation area), this function prints | |
1da7358e | 40 | the total amount of memory allocated |
067568db MK |
41 | and the total number of bytes consumed by in-use allocations. |
42 | (These two values correspond to the | |
43 | .I arena | |
44 | and | |
45 | .I uordblks | |
46 | fields retrieved by | |
47 | .BR mallinfo (3).) | |
48 | In addition, | |
49 | the function prints the sum of these two statistics for all arenas, | |
50 | and the maximum number of blocks and bytes that were ever simultaneously | |
51 | allocated using | |
52 | .BR mmap (2). | |
