SYNOPSIS

       #include <volpack.h>

ARGUMENTS

       vpc    VolPack context from vpCreateContext.

       code   A VolPack error result code.

DESCRIPTION

       These  routines  are  used  for error handling.  vpGetError return the error code from the first function
       call that failed since the last call  to  vpGetError.   vpGetErrorString  returns  a  descriptive  string
       corresponding  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.
