.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
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.
.SH "INTERFACE"
.IX Header "INTERFACE"
.Sh "\fItestallocate()\fP"
.IX Subsection "testallocate()"
This exportable function takes one argument: the number of megabytes to try and allocate betwen 1 and 1024
.PP
It returns the number of allocated megabytes.
.PP
If they are not the same then the allocation had issues ( see \s-1SYNOPSIS\s0 )
.SH "DIAGNOSTICS"

.el .IP "\f(CWUnable to allocate %d Megabytes of memory (Invalid Argument)\fR" 4
.IX Item "Unable to allocate %d Megabytes of memory (Invalid Argument)"
Invalid argument was passed to \fItestallocate()\fR (\s-1IE\s0 it is not 1 .. 1024)
.ie n .IP """Error while allocating memory! %d Megabytes already allocated""" 4
.el .IP "\f(CWError while allocating memory! %d Megabytes already allocated\fR" 4
.IX Item "Error while allocating memory! %d Megabytes already allocated"
There was not enough free memory left to allocate the amount you requested.
