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.

ERORS
     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.
