-.TH MALLOC_TRIM 3 2014-05-28 "Linux" "Linux Programmer's Manual"
-.SH NAME
-malloc_trim \- release free memory from the top of the heap
-.SH SYNOPSIS
-.B #include <malloc.h>
-
-.BI "int malloc_trim(size_t " pad );
-.SH DESCRIPTION
-The
-.BR malloc_trim ()
-function attempts to release free memory at the top of the heap
-(by calling
-.BR sbrk (2)
-with a suitable argument).
-
-The
-.I pad
-argument specifies the amount of free space to leave untrimmed
-at the top of the heap.
-If this argument is 0, only the minimum amount of memory is maintained
-at the top of the heap (i.e., one page or less).
-A nonzero argument can be used to maintain some trailing space
-at the top of the heap in order to allow future allocations
-to be made without having to extend the heap with
-.BR sbrk (2).
-.SH RETURN VALUE
-The
-.BR malloc_trim ()
-function returns 1 if memory was actually released back to the system,
-or 0 if it was not possible to release any memory.
-.SH ERRORS
-No errors are defined.
-.\" .SH VERSIONS
-.\" Available already in glibc 2.0, possibly earlier
-.SH CONFORMING TO
-This function is a GNU extension.
-.SH NOTES
-This function is automatically called by
-.BR free (3)
-in certain circumstances; see the discussion of
-.B M_TOP_PAD
-and
-.B M_TRIM_THRESHOLD
-in
-.BR mallopt (3).
-
-This function cannot release free memory located at places
-other than the top of the heap.
-
-This function releases only memory in the main arena.
