int parse_arguments(char *buf, size_t len, char *params[50])
static void hexify(unsigned char *obuf, const unsigned char *ibuf, int len)
Info structure for the pseudo random function.
static int rnd_std_rand(void *rng_state, unsigned char *output, size_t len)
This function just returns data from rand().
void memory_buffer_alloc_free(void)
Free the mutex for thread-safety and clear remaining memory.
static int rnd_zero_rand(void *rng_state, unsigned char *output, size_t len)
This function only returns zeros.
static unsigned char * unhexify_alloc(const char *ibuf, size_t *olen)
Allocate and fill a buffer from hex data.
