Mathematical Library Functions                                fetestexcept(3M)



NAME
       fetestexcept - test floating-point exception flags

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <fenv.h>

       int fetestexcept(int excepts);

DESCRIPTION
       The  fetestexcept()  function determines which of a specified subset of
       the floating-point exception flags are currently set. The excepts argu‐
       ment specifies the floating-point status flags to be queried.

RETURN VALUES
       The  fetestexcept() function returns the value of the bitwise-inclusive
       OR of the floating-point exception macros  corresponding  to  the  cur‐
       rently set floating-point exceptions included in excepts.

ERRORS
       No errors are defined.

EXAMPLES
       Example 1 Example using fetestexcept()



       The  following  example  calls function f( ) if an invalid exception is
       set, and then function g( ) if an overflow exception is set:


         #include <fenv.h>
         /* ... */
         {
         #     pragma STDC FENV_ACCESS ON
               int set_excepts;
               feclearexcept(FE_INVALID | FE_OVERFLOW);
               // maybe raise exceptions
               set_excepts = fetestexcept(FE_INVALID | FE_OVERFLOW);
               if (set_excepts & FE_INVALID) f();
               if (set_excepts & FE_OVERFLOW) g();
               /* ... */
         }
