feraiseexcept(3M) Mathematical Library Functions feraiseexcept(3M)
NAME
feraiseexcept - raise floating-point exception
SYNOPSIS
cc [ flag... ] file... -lm [ library... ]
#include <fenv.h>
int feraiseexcept(int excepts);
DESCRIPTION
The feraiseexcept() function attempts to raise the supported floating-point exceptions represented by the excepts argument. The order in
which these floating-point exceptions are raised is unspecified.
RETURN VALUES
If excepts is 0 or if all the specified exceptions were successfully raised, feraiseexcept() returns 0. Otherwise, it returns a non-zero
value.
ERRORS
No errors are defined.
USAGE
The effect is intended to be similar to that of floating-point exceptions raised by arithmetic operations. Hence, enabled traps for float-
ing-point exceptions raised by this function are taken.
