Psuedo-Random Number Functions

These functions implement the libnet pseudo-random number interface.

int libnet_seed_prand(libnet_t *1);

libnet_seed_prand() seeds libnet's pseudo-random number generator with a call to gettimeofday(), which provides more entropy than time(). Upon success, the function returns 1; upon failure, the function returns -1 and libnet_geterror() tells you that gettimeofday() failed.

u_long libnet_get_prand(int type);

libnet_get_prand() returns a positive pseudo-random number within the range specified in type, as summarized in Table 3.55.
