NAMEkillpg — send signal to a process group
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include <sys/types.h> #include <signal.h> int killpg(pid_t pgrp, int sig);
DESCRIPTIONThe killpg() function sends the signal sig to the process group pgrp. See sigaction(2) for a list of signals. If pgrp is 0, killpg() sends the signal to the sending process's process group. The sending process must be able to kill() at least one process in the receiving process group.
RETURN VALUESThe killpg() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORSThe killpg() function will fail and no signal will be sent if: [EINVAL] The sig argument is not a valid signal number. [ESRCH] No process can be found in the process group specified by pgrp. [EPERM] kill() returns EPERM for all processes in the process group.
