The value pointed to by \fIflagp\fR will have been set by a previous call to \fBfegetexceptflag()\fR whose second argument represented at least those floating-point exceptions represented by the \fIexcepts\fR argument. This function does not raise floating-point exceptions but only sets the state of the flags. .SH RETURN VALUES .sp .LP If the representation was successfully stored, \fBfegetexceptflag()\fR returns 0. Otherwise, it returns a non-zero value. .sp .LP If the excepts argument is 0 or if all the specified exceptions were successfully set, \fBfesetexceptflag()\fR returns 0. Otherwise, it returns a non-zero value. .SH ERRORS .sp .LP No errors are defined. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
