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.
