18.3 Auxiliary quasi-random number generator functions

Function: const char * gsl_qrng_name (const gsl_qrng * q)
This function returns a pointer to the name of the generator.
Function: size_t gsl_qrng_size (const gsl_qrng * q)
Function: void * gsl_qrng_state (const gsl_qrng * q)
These functions return a pointer to the state of generator r and its size. You can use this information to access the state directly. For example, the following code will write the state of a generator to a stream,
void * state = gsl_qrng_state (q);
size_t n = gsl_qrng_size (q);
fwrite (state, n, 1, stream);
