NAME

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.
