<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>malloc_stats</B>()
|
|
|
|
function prints (on standard error) statistics about memory allocated by
|
|
<B><A HREF="/cgi-bin/man/man2html?3+malloc">malloc</A></B>(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</I>
|
|
|
|
and
|
|
<I>uordblks</I>
|
|
|
|
fields retrieved by
|
|
<B><A HREF="/cgi-bin/man/man2html?3+mallinfo">mallinfo</A></B>(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
|
|
<B><A HREF="/cgi-bin/man/man2html?2+mmap">mmap</A></B>(2).
