Hey guys,
I'm trying to merge the output from the ps and top commands; since I need the full command used (only showed in the ps), and the cpu usage with some decimal numbers (i.e.: 0.05%, only showed in top).
After exporting to different files, I was thinking of doing an egrep with the... (0 Replies)

Solaris experts,
Am struggling, and wondering for the past more than one week that, how to calculate the total available and used memory/swap space.
Finally installed and used top & got some understanding, but while cross-checking, there are mismatches.

malloc_trim
MALLOC_TRIM(3) Linux Programmer's Manual MALLOC_TRIM(3)NAME
malloc_trim - release free memory from the top of the heap
SYNOPSIS
#include <malloc.h>
int malloc_trim(size_t pad);
DESCRIPTION
The malloc_trim() function attempts to release free memory at the top of the heap (by calling sbrk(2) with a suitable argument).
The 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 sbrk(2).
RETURN VALUE
The 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.
ERRORS
No errors are defined.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
This function is a GNU extension.
NOTES
This function is automatically called by free(3) in certain circumstances; see the discussion of M_TOP_PAD and M_TRIM_THRESHOLD in mal-
lopt(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.
