       vpGetError, vpGetErrorString - retrieve error codes

SYNOPSIS

       #include <volpack.h>

       vpResult
       vpGetError(vpc)
           vpContext *vpc;

       char *
       vpGetErrorString(code)
           vpResult code;

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.
