Process Information
-------------------

 - Function: process-id process-object
     This function returns the operating-system identifier associated
     with the subprocess currently running on the process object
     PROCESS-OBJECT.

 - Function: process-exit-value process-object
     Returns the integer representing the return code of the last
     subprocess to be run on PROCESS-OBJECT.

     If no subprocess has been run on PROCESS-OBJECT, PROCESS-OBJECT is
     currently in the running state or the last subprocess exited
     abnormally (i.e. from a terminal signal) false is returned.

 - Function: process-exit-status process-object
     This function returns the integer that was the exit status of the
     last subprocess which was run on the process object PROCESS-OBJECT.

     Note that the exit status is _not_ the value given to the `exit'
     function in a C program, use the `process-exit-value' to access
     this value.

     If no process has been run on PROCESS-OBJECT, or the process is
     currently in the running state false is returned.
