Mathematical Library Functions feraiseexcept(3M)
NAME
feraiseexcept - raise floating-point exception
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include
int feraiseexcept(int excepts);
DESCRIPTION
The feraiseexcept() function attempts to raise the supported
floating-point exceptions represented by the excepts argu-
ment. 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 suc-
cessfully 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.ATTRIBUTES
