PURPOSE

Execute the command line and create a fifo pipe for reading/writing

SYNOPSIS

This is a script file.

DESCRIPTION

 Execute the command line and create a fifo pipe for reading/writing
 output/input. Used internally by pfstools.

 fid = pfspopen( command_line, mode )
 
   command_line - shell command line that should be executed
   mode - either 'r' for reading output, or 'w' for writing input
   fid - file ID, which should be passed to pfsopen

 Always use pfspclose() to close the pipe created with pfspopen
