cPanel::MemTest - Test Memory Allocation
This document describes cPanel::MemTest version 0.0.2
use cPanel::MemTest; my $megs_to_allocate = 200; my $megs_allocated = cPanel::MemTest::testallocate( $megs_to_allocate ); die 'There was a problem allocating memory' if $megs_allocated != $megs_to_allocate;
If you know you'll be running a memory intensive script it can be nice to be able to see if there is enough memory first instead of hitting a memory limit partway through and failing with little or no control over it.
This exportable function takes one argument: the number of megabytes to try and allocate betwen 1 and 1024
It returns the number of allocated megabytes.
If they are not the same then the allocation had issues ( see SYNOPSIS )
Unable to allocate %d Megabytes of memory (Invalid Argument)
Invalid argument was passed to testallocate() (IE it is not 1 .. 1024)
Error while allocating memory! %d Megabytes already allocated
There was not enough free memory left to allocate the amount you requested.
cPanel::MemTest requires no configuration files or environment variables.
No bugs have been reported.
