FEHOLDEXCEPT(P)		   POSIX Programmer's Manual	       FEHOLDEXCEPT(P)

NAME
       feholdexcept - save current floating-point environment

SYNOPSIS
       #include <fenv.h>

       int feholdexcept(fenv_t *envp);

DESCRIPTION
       The feholdexcept() function shall save the current floating-point envi‐
       ronment in the object pointed to by envp, clear the floating-point sta‐
       tus  flags,  and	 then  install	a non-stop (continue on floating-point
       exceptions) mode, if available, for all floating-point exceptions.

RETURN VALUE
       The feholdexcept() function shall return zero if and only  if  non-stop
       floating-point exception handling was successfully installed.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       None.

RATIONALE
       The   feholdexcept()   function	 should	  be   effective   on  typical
       IEC 60559:1989 standard implementations which have the default non-stop
       mode  and at least one other mode for trap handling or aborting. If the
       implementation provides only the non-stop  mode,	 then  installing  the
       non-stop mode is trivial.

FUTURE DIRECTIONS
       None.
