Return Values
- VSL_ERROR_OK,VSL_STATUS_OK
- Indicates no error, execution is successful.
- VSL_ERROR_NULL_PTR
- streamis aNULLpointer.
- VSL_RNG_ERROR_BAD_STREAM
- streamis not a valid random stream.
- VSL_RNG_ERROR_BAD_UPDATE
- Callback function for an abstract BRNG returns an invalid number of updated entries in a buffer, that is,< 0or>.nmax
- VSL_RNG_ERROR_NO_NUMBERS
- Callback function for an abstract BRNG returns 0 as the number of updated entries in a buffer.
- VSL_RNG_ERROR_QRNG_PERIOD_ELAPSED
- Period of the generator has been exceeded.
- VSL_RNG_ERROR_NONDETERM_NRETRIES_EXCEEDED
