setpgrp3 - create session and set process group ID; for HP-UX 9.x
If the calling process is not a process group leader, setpgrp3()
creates a new session. The calling process becomes the session leader
of this new session, it becomes the process group leader of a new
process group, and it has no controlling terminal. The process group
ID of the calling process is set equal to the process ID of the
calling process. The calling process is the only process in the new
process group, and the only process in the new session.
setpgrp3() function is provided for HP-UX compatibility in future
releases. setpgrp3() is functionally equivalent to setpgrp() as
provided in HP-UX 9.x.
Upon successful completion, setpgrp3() returns the value of the
process group ID of the calling process. Otherwise, it returns a
value of -1, and sets errno to indicate the error.
No errors are defined.
setpgrp3() is to be obsoleted at a future date.
setpgrp3() was developed by HP.
