FUNCTION
<<feraiseexcept>>---raise floating-point exception
INDEX
feraiseexcept
SYNOPSIS
#include <fenv.h>
int feraiseexcept(int <[excepts]>);
Link with -lm.
DESCRIPTION
This method attempts to raise the floating-point exceptions specified
in <[excepts]>.
RETURNS
If the <[excepts]> argument is zero or all requested exceptions were
successfully raised, this method returns zero. Otherwise, a non-zero
value is returned.
PORTABILITY
ANSI C requires <<feraiseexcept>>.
Not all Newlib targets have a working implementation. Refer to
the file <<sys/fenv.h>> to see the status for your target.
*/
/*
* This is a non-functional implementation that should be overridden
* by an architecture specific implementation in newlib/libm/machine/ARCH.
*/
