NAME

       fegettrapenable() - get floating-point exception trap enables

SYNOPSIS

DESCRIPTION

       The function determines which floating-point exception traps are currently enabled.

USAGE

       To use this function, compile either with the default option or with the and options.  Make sure your program includes

       For  HP	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

       The  function  returns  the  bitwise OR of the floating-point exception macros corresponding to the currently enabled exception traps.  The
       macros are and represents all the floating-point exceptions.

ERRORS

       No errors are defined.

EXAMPLES

       Retrieve the current trap settings and determine whether a trap for the divide by zero exception is enabled.

NAME

       fegetexceptflag() - get floating-point exception flags

SYNOPSIS

   HP Integrity Server Only
   PA-RISC Only
DESCRIPTION

       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 constructed as a bitwise OR of the floating-point exception macros: and rep-
       resents 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 unspecified.

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

USAGE

       To use this function, compile either with the default option or with the and options.  Make sure your program includes

RETURN VALUE

   Integrity Server Only
       This function always returns 0, indicating that a representation was successfully stored.

   PA-RISC Only
       None.

ERRORS

       No errors are defined.

EXAMPLES

       Store the overflow and invalid floating-point exception flags:
