26 * Curl_rand() stores 'num' number of random unsigned characters in the buffer
27 * 'rnd' points to.
28 *
29 * If libcurl is built without TLS support or with a TLS backend that lacks a
30 * proper random API (Gskit, PolarSSL or mbedTLS), this function will use
31 * "weak" random.
32 *
33 * When built *with* TLS support and a backend that offers strong random, it
34 * will return error if it cannot provide strong random values.
35 *
36 * NOTE: 'data' may be passed in as NULL when coming from external API without
37 * easy handle!
