The help(Random.user) page says Optionally, the user can supply the entry point 'user_unif_init', which is called with an 'unsigned int' argument when 'RNGkind' (or 'set.seed') is called, and is intended to be used to initialize the user's RNG code. The argument is intended to be used to set the "seeds"; it is the 'seed' ar...

...compact (but still brittle) way to match function declarations in C header files is shown at the end of this message. I have confirmed that compared to tools:::getFunsHdr, the only extraneous symbols that it finds in preprocessed headers are "R_SetWin32", "user_unif_rand", "user_unif_init", "user_unif_nseed", "user_unif_seedloc" "user_norm_rand", which are special-cased in tools:::getFunsHdr, and the only symbols it doesn't find are "select" and "delztg" in R_ext/Lapack.h, which we should not be finding. # "Bird's...

..._seedloc} can be supplied which are called with no arguments and should return pointers to the number of seeds and to an integer array of seeds. Calls to \code{GetRNGstate} and \code{PutRNGstate} will then copy this array to and from \code{.Random.seed}. And it offers as an example void user_unif_init(Int32 seed_in) { seed = seed_in; } int * user_unif_nseed() { return &nseed; } int * user_unif_seedloc() { return (int *) &seed; } First question: what is the lifetime of the buffers pointed to by the user_unif-* functions, and who is responsible for cleaning them up? In the help file...
