NAME
       fesetexceptflag() - set floating-point exception flags

SYNOPSIS
   HP Integrity Server Only
   PA-RISC Only
DESCRIPTION
       The  function  sets  the status for the floating-point exception flags indicated by the argument excepts to the states stored in the object
       pointed to by flagp.  The value of *flagp must have been set by a previous call to whose second argument represented at least those  float-
       ing-point  exceptions  represented  by the argument excepts; otherwise, the effect on the indicated floating-point exception flags is unde-
       fined.  This function does not raise exceptions, but only sets the state of the flags (hence no traps will be taken).  The excepts argument
       can be constructed as a bitwise OR of the floating-point exception macros: and represents all the floating-point exceptions.

USAGE
       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 statement), 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 in order to prevent optimizations that can undermine the specified behavior of this function.

       Link in the math library by specifying on the compiler or linker command line.

RETURN VALUE
   Integrity Server Only
       This function always returns 0, indicating that all the specified flags were successfully set to the appropriate state.

   PA-RISC Only
       None.

ERRORS
       No errors are defined.

EXAMPLES
       Use to save the current state of two floating-point exception flags.  Later, use to restore the saved state.
