static int rnd_buffer_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function returns random based on a buffer it receives.

rng_state shall be a pointer to a rnd_buf_info structure.

The number of bytes released from the buffer on each call to the random function is specified by per_call. (Can be between 1 and 4)

After the buffer is empty it will return rand();

static int rnd_pseudo_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function returns random based on a pseudo random function.

This means the results should be identical on all systems. Pseudo random is based on the XTEA encryption algorithm to generate pseudorandom.

rng_state shall be a pointer to a rnd_pseudo_info structure.

static int rnd_std_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function just returns data from rand().

Although predictable and often similar on multiple runs, this does not result in identical random on each run. So do not use this if the results of a test depend on the random data that is generated.

rng_state shall be NULL.

This function only returns zeros.

static unsigned char* unhexify_alloc ( const char *  ibuf,
size_t *  olen 
)
static

Allocate and fill a buffer from hex data.

The buffer is sized exactly as needed. This allows to detect buffer overruns (including overreads) when running the test suite under valgrind.

If the size if zero, a pointer to a zeroized 1-byte buffer is returned.

For convenience, dies if allocation fails.
