FERAISEEXCEPT 3M "Jul 12, 2006" "SunOS 5.11" "Mathematical Library Functions"
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.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
| ATTRIBUTE TYPE ATTRIBUTE VALUE |
| Interface Stability Standard |
| MT-Level MT-Safe |
