DESCRIPTION
       These  routines are used	for error handling.  vpGetError	return the er-
       ror code	from the first function	call that failed since the  last  call
       to  vpGetError.	 vpGetErrorString  returns a descriptive string	corre-
       sponding	to an error code.  The string is stored	in a global  array  so
       it does not need	to be copied to	separate memory.

ERRORS
       vpGetError  cannot  fail.  A return value not equal to VP_OK means that
       some previous function call has failed.	vpGetErrorString returns  NULL
       if code is invalid.
