Short: Processing stacksize in cli-scripts
Author: Thomas.Radtke@rz.uni-osnabrueck.de
Uploader: Thomas.Radtke@rz.uni-osnabrueck.de
Type: util/batch
This command lets you process the stacksize in cli-scripts. If the
numeric argument given to it is lower than the actual stacksize, it
will exit with value 5.
Usage:
syntax: stacksize n
returncode: 5 if stacksize is lower than n, or if n is missing
0 if stacksize is higher or equal to n
Example: You want to start a command in a batch file wich will use
20KB of stack. Normally you are using 4KB of stack, but maybe the user
has raised the size to 300KB to start e.g. maple from the shell, you don't
know. Setting the stack at this point to 20KB will be deadly for the
one really starting maple after executing your batch file. To avoid
such problems, you could now use the following script:
; This example raises the stacksize only if it ranges below a critical
; value
stacksize 20480 ; request the return code
if warn ; stack was lower than 20KB ?
stack 20480 ; yes, raise the stack
endif
Installation: Just move or copy bin/stacksize anywhere in your path,
e.g. cp bin/stacksize c:
The source can be found in the src directory.
Legal: stacksize is freeware, you can redistribute the archive as
long as the files 'stacksize' and 'stacksize.readme' are intact.
