Otherwise, \fB\(mi1\fR is returned and \fBerrno\fR is set to indicate the error. .SH ERRORS .sp .LP The \fBtcgetpgrp()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBEBADF\fR\fR .ad .RS 10n .rt The \fIfildes\fR argument is not a valid file descriptor. .RE .sp .ne 2 .mk .na \fB\fBENOTTY\fR\fR .ad .RS 10n .rt The calling process does not have a controlling terminal, or the file is not the controlling terminal. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
