- The process group of the specified process is returned by ggeettppggrrpp(). If
- _p_i_d is zero, the call applies to the current process.
-
- Process groups are used for distribution of signals, and by terminals to
- arbitrate requests for their input: processes that have the same process
- group as the terminal are foreground and may read, while others will
- block with a signal if they attempt to read.
-
- This call is thus used by programs such as csh(1) to create process
- groups in implementing job control. The TIOCGPGRP and TIOCSPGRP calls
- described in termios(4) are used to get/set the process group of the conĀ
- trol terminal.
