tcsetpgrp

tcsetpgrp(3C)															     tcsetpgrp(3C)

NAME

       tcsetpgrp() - set foreground process group id

SYNOPSIS

DESCRIPTION

       If  the	calling process has a controlling terminal, sets the foreground process group ID associated with the terminal referenced by fildes
       to pgrp_id.  The file associated with fildes must be the controlling terminal of the calling process and the controlling terminal  must	be
       currently  associated with the session of the calling process.  The value of pgrp_id must match a process group ID of a process in the same
       session as the calling process.

RETURN VALUE

       Upon successful completion, returns zero.  Otherwise, returns -1 and sets to indicate the error.

ERRORS

       fails if any of the following conditions are encountered:

	      [EBADF]	     fildes is not a valid file descriptor.

	      [EINVAL]	     The value of the pgrp_id argument is not supported.

	      [ENOTTY]	     The calling process does not have a controlling terminal, or the fildes is not the controlling terminal, or the  con-
			     trolling terminal is no longer associated with the session of the calling process.

	      [EPERM]	     The value of pgrp_id is a supported value but does not match the process group ID of a process in the same session as
			     the calling process.
