+.SH NAME
+tcgetpgrp \- get the foreground process group ID
+.SH SYNOPSIS
+.LP
+\fB#include <unistd.h>
+.br
+.sp
+pid_t tcgetpgrp(int\fP \fIfildes\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fItcgetpgrp\fP() function shall return the value of the process
+group ID of the foreground process group associated with
+the terminal.
+.LP
+If there is no foreground process group, \fItcgetpgrp\fP() shall return
+a value greater than 1 that does not match the process
+group ID of any existing process group.
+.LP
+The \fItcgetpgrp\fP() function is allowed from a process that is a
+member of a background process group; however, the
+information may be subsequently changed by a process that is a member
+of a foreground process group.
+.SH RETURN VALUE
+.LP
+Upon successful completion, \fItcgetpgrp\fP() shall return the value
+of the process group ID of the foreground process
+associated with the terminal. Otherwise, -1 shall be returned and
+\fIerrno\fP set to indicate the error.
+.SH ERRORS
+.LP
+The \fItcgetpgrp\fP() function shall fail if:
+.TP 7
+.B EBADF
+The \fIfildes\fP argument is not a valid file descriptor.
+.TP 7
+.B ENOTTY
+The calling process does not have a controlling terminal, or the file
+is not the controlling terminal.
