GETPGRP(2) BSD System Calls Manual GETPGRP(2) NAME getpgrp -- get process group SYNOPSIS pid_t getpgrp(int pid); DESCRIPTION The process group of the specified process is returned by getpgrp(). If pid 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 con- trol terminal. SEE ALSO setpgrp(2), getuid(2), termios(4) HISTORY The getpgrp function call appeared in 4.0BSD. 4.2 Berkeley Distribution March 10, 1991 4.2 Berkeley Distribution
