FYI, there is also this, for a human-readable string:

/**
 * \brief Retrieve a string describing an error code.
 * \param[in] status The error code.
 * \return A pointer to the string. Note that this is a 
 *       statically allocated read-only string. As such, the
 *       application must not free the returned pointer. The
 *       pointer is valid as long as the VDPAU implementation is
 *       present within the application's address space.
 */
typedef char const * VdpGetErrorString(
    VdpStatus status
);
