+.SH DESCRIPTION
+.LP
+The \fIposix_spawnattr_getpgroup\fP() function shall obtain the value
+of the \fIspawn-pgroup\fP attribute from the attributes
+object referenced by \fIattr\fP.
+.LP
+The \fIposix_spawnattr_setpgroup\fP() function shall set the \fIspawn-pgroup\fP
+attribute in an initialized attributes object
+referenced by \fIattr\fP.
+.LP
+The \fIspawn-pgroup\fP attribute represents the process group to be
+joined by the new process image in a spawn operation (if
+POSIX_SPAWN_SETPGROUP is set in the \fIspawn-flags\fP attribute).
+The default value of this attribute shall be zero.
+.SH RETURN VALUE
+.LP
+Upon successful completion, \fIposix_spawnattr_getpgroup\fP() shall
+return zero and store the value of the \fIspawn-pgroup\fP
+attribute of \fIattr\fP into the object referenced by the \fIpgroup\fP
+parameter; otherwise, an error number shall be returned to
+indicate the error.
+.LP
+Upon successful completion, \fIposix_spawnattr_setpgroup\fP() shall
+return zero; otherwise, an error number shall be returned
+to indicate the error.
+.SH ERRORS
+.LP
+These functions may fail if:
+.TP 7
+.B EINVAL
+The value specified by \fIattr\fP is invalid.
+.sp
+.LP
+The \fIposix_spawnattr_setpgroup\fP() function may fail if:
+.TP 7
+.B EINVAL
+The value of the attribute being set is not valid.
