NAME
fegetexceptflag() - get floating-point exception flags
SYNOPSIS
#include <fenv.h>
void fegetexceptflag(fexcept_t *flagp, int excepts);
DESCRIPTION
The fegetexceptflag() function stores the exception flags indicated by the argument excepts in the
object pointed to by the argument flagp. The excepts argument can be constructed as a bitwise OR of the
exception macros: FE_INEXACT, FE_DIVBYZERO , FE_UNDERFLOW , FE_OVERFLOW , and
FE_INVALID. FE_ALL_EXCEPT represents all the exceptions.
Use fetestexcept() to determine which exception flags are set.
The ISO/ANSI C committee has approved the fegetexceptflag() function for inclusion in the C9X
draft standard.
To use this function, compile either with the default
-Ae option or with the -Aa and -D_HPUX_SOURCE
options. Make sure your program includes <fenv.h
>. Link in the math library by specifying -lm on the
compiler or linker command line.
For more information, see the HP-UX Floating-Point Guide.
RETURN VALUE
None.
ERRORS
No errors are defined.
EXAMPLE
Store the overflow and invalid exception flags:
#include <fenv.h>
/*...*/
fexcept_t flags;
/*...*/
fegetexceptflag(&flags, FE_OVERFLOW | FE_INVALID);
