       fegetexceptflag() - get floating-point exception flags

   HP Integrity Server Only
   PA-RISC Only
       The  function  stores  a	 representation of the states of the floating-
       point exception flags indicated by the argument excepts in  the	object
       pointed	to  by	the  argument flagp.  The excepts argument can be con‐
       structed as a bitwise OR of the floating-point  exception  macros:  and
       represents  all	the  floating-point exceptions.	 The object into which
       the floating-point exception flags are  stored  can  be	passed	to  to
       restore	the  system  exception	flags,	but  the representation of the
       floating-point exception	 flags	stored	in  the	 object	 is  otherwise

       Use  instead  of	 to determine which floating-point exception flags are

       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 compiler option in order to pre‐
       vent optimizations that can undermine the specified  behavior  of  this

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