- NAME
- setsid, getpgrp - create process group, get process group id
- SYNOPSIS
- #include <sys/types.h>
- #include <unistd.h>
- pid_t setsid(void)
- pid_t getpgrp(void)
- DESCRIPTION
- Setsid() creates a new session if the calling process is not already a
- session leader. The calling process becomes the session leader of a new
- process group and the process group ID of this new process group will be
- equal to the process ID of the new session leader. The process group ID
- is inherited on a fork().
- Getpgrp() returns the process group ID of the calling process.
- SEE ALSO
- kill(2), termios(3), tty(4).
- DIAGNOSTICS
- Setsid() returns the new process group ID on success, or -1 with errno
- set to EPERM if the process is already a session leader.
