I've written the man page page below to document glibc's malloc_stats(3). Review comments welcome!

For each arena (allocation area), this function prints the total amount of memory allocated by means other than .BR mmap (2) 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 CONFORMING TO This function is a GNU extension. .SH NOTES More detailed information about memory allocations in the main arena can be obtained using .BR mallinfo (3). .SH SEE ALSO .BR mmap (2), .BR mallinfo (3), .BR malloc (3), .BR malloc_info (3), .BR mallopt (3)
