PROCESS_GETINFO_ Procedure
a mom process if a mom process has been explicitly assigned by either the
PROCESS_SETINFO_ or STEPMOM procedure.
Home Terminal Considerations
•
The home-terminal file name returned by PROCESS_GETINFO_ is in a form
suitable for passing directly to file-system procedures such as FILE_OPEN_.
•
The home terminal is always the same as the home terminal of the original creator
(not stepmom) of the process unless the home terminal is altered by a call to
PROCESS_SETSTRINGINFO_, SETMYTERM, PROCESS_DEBUG_ or
DEBUGPROCESS, or the home terminal option is supplied to
PROCESS_CREATE_, PROCESS_SPAWN_, NEWPROCESS,
NEWPROCESSNOWAIT, OSS
tdm_fork(), OSS tdm_spawn(), or one of the
OSS
tdm_exec set of functions.
I/O Processes That Control Multiple Devices
•
If processhandle is an I/O process that controls multiple devices, the returned
proc-fname is the name of the first device controlled by that I/O process.
OSS Considerations
•
Use this procedure to find out if a process is an OSS process and to retrieve the
OSS process ID associated with the process handle.
•
An OSS process can change its processor,pin value during its lifetime. Zombie
processes are not returned, because processor,pin pairs are not defined for
zombie processes. The OSS process ID is a unique identifier representing an OSS
process. It is a positive integer. It is not reused by the system until the process
lifetime ends. A zombie process is an inactive process that will be deleted by its
parent process.
Example
error := PROCESS_GETINFO_ ( proc^handle ,
proc^descriptor:maxlen ,
proc^desc^length , ,
moms^proc^handle , , , , , ,
gmoms^proc^handle , jobid );
