NAME

       feraiseexcept() - raise floating-point exceptions

SYNOPSIS

   HP Integrity Server Only
   PA-RISC Only
DESCRIPTION

       The  function  raises  the  floating-point  exceptions represented by its argument.  The argument can be constructed as a bitwise OR of the
       exception macros: and represents all the exceptions.

       Any traps enabled for the specified exceptions will be taken.

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 compiler option 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 exceptions were successfully raised.

   PA-RISC Only
       None.

ERRORS

       No errors are defined.

EXAMPLES

       Raise the underflow and inexact exceptions:

       Raise all exceptions:
