       fegetenv() - get floating-point environment

   HP Integrity Server Only
   PA-RISC Only
       The  function  stores  the  current  floating-point  environment in the
       object pointed to by the argument envp.

       To use this function, compile either with the default  option  or  with
       the and options.

       Make sure your program includes

       For  Integrity  servers,	 specify on the compiler command line or place
       the call to this function under the effect of an affirmative pragma:

       If the pragma is placed outside of  any	top-level  declarations	 in  a
       file, the pragma will apply to all declarations in the compilation fol‐
       lowing the pragma until another pragma is encountered or until the  end
       of the file is reached.

       If  the	pragma	is placed at the beginning of a block (compound state‐
       ment), the pragma will apply until another  pragma  is  encountered  or
       until the end of the block is reached.

       For PA-RISC, you might need to use the +Onomoveflops compiler option in
       order to prevent optimizations that can undermine the specified	behav‐
       ior of this function.

       Link  in	 the math library by specifying on the compiler or linker com‐
       mand line.
