NAME
feraiseexcept - raise floating-point exception
SYNOPSIS
c99 [
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
floating-point exceptions raised by this function are taken.
