NAME

getpgrp − get process group

SYNOPSIS

pgrp = getpgrp(pid)
int prgp;
int pid;

DESCRIPTION

The process group of the specified process is returned by getpgrp.  If pid is zero, then 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 which 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.
