18 | .SH DESCRIPTION |
| 19 | The | |
| 20 | .BR malloc_stats () | |
| 21 | function prints (on standard error) statistics about memory allocated by | |
| 22 | .BR malloc (3) | |
| 23 | and related functions. | |
| 24 | For each arena (allocation area), this function prints | |
| 1da7358e | 25 | the total amount of memory allocated |
| 067568db MK |
26 | and the total number of bytes consumed by in-use allocations. |
| 27 | (These two values correspond to the | |
| 28 | .I arena | |
| 29 | and | |
| 30 | .I uordblks | |
| 31 | fields retrieved by | |
| 32 | .BR mallinfo (3).) | |
| 33 | In addition, | |
| 34 | the function prints the sum of these two statistics for all arenas, | |
| 35 | and the maximum number of blocks and bytes that were ever simultaneously | |
| 36 | allocated using | |
| 37 | .BR mmap (2). | |
