Fri Dec 19 11:49:21 2003 George Lebl <jirka@5z.com> * glib/grand.c glib/grand.h (g_rand_new) (g_rand_new_with_seed) (g_rand_new_with_seed_array) (g_rand_set_seed_array): Add the init_by_array functionality from the reference implementation of the mersenne twister (mt19937ar.c) and change the naming to fit with the rest of the grand API. New functions are g_rand_new_with_seed_array, g_rand_set_seed_array. This is only reliable/tested for the 2.2 version of the seeding as that's what the reference implementation uses. Also modify g_rand_new to get 4 longs from /dev/urandom since that will always be available anyway and we get more entropy and if /dev/urandom is unavailable use also 4 longs for seeding using secs, usecs, getpid and getppid. For version 2.0 use only a simple seed again but be more careful ...
