.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"
.SS "\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)
