NAME
       feholdexcept - save current floating-point environment

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

       int feholdexcept(fenv_t *envp);

DESCRIPTION
       The  feholdexcept()  function saves the current floating-point environ‐
       ment in the object pointed to by envp, clears the floating-point status
       flags,  and then installs a non-stop (continue on floating-point excep‐
       tions) mode, if available, for all floating-point exceptions.

RETURN VALUES
       The feholdexcept() function returns 0 if and only if non-stop floating-
       point exception handling was successfully installed.

ERRORS
       No errors are defined.

NOTES
       In a multithreaded program, the	feholdexcept()	function  affects  the
       floating point environment only for the calling thread.

       The  feholdexcept()  function  automatically  installs  and  deinstalls
       SIGFPE handlers and sets and clears the trap enable mode	 bits  in  the
       floating point status register as needed. If a program uses these func‐
       tions and attempts to install a SIGFPE  handler	or  control  the  trap
       enable mode bits independently, the resulting behavior is not defined.
