Overview
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.
