ARGUMENTS

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.
