- A VolPack error result code.
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.
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.
