On entry: contains information on the selected base generator and its current state.
On exit: contains updated information on the state of the generator.
3: – NagError *Input/Output
The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).
6Error Indicators and Warnings
Dynamic memory allocation failed.
See Section 3.1.2 in the Introduction to the NAG Library CL Interface for further information.
On entry, the state vector defined on initialization is not large enough to perform a skip-ahead (applies to Mersenne Twister base generator). See the initialization function g05kfcorg05kgc.
On entry, argument had an illegal value.
On entry, .
On entry, cannot use skip-ahead with the base generator defined by state.
An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
See Section 7.5 in the Introduction to the NAG Library CL Interface for further information.
On entry, state vector has been corrupted or not initialized.
Your licence key may have expired or may not have been installed correctly.

8Parallelism and Performance
g05kkc is not threaded in any implementation.
Calling g05kkc and then generating a series of uniform values using g05sac is equivalent to, but more efficient than, calling g05sac and discarding the first values. This may not be the case for distributions other than the uniform, as some distributional generators require more than one uniform variate to generate a single draw from the required distribution.
This example initializes a base generator using g05kfc and then uses g05kkc to advance the sequence places before generating five variates from a uniform distribution using g05sac.
