For best security, QNX recommends you use the QNX Neutrino random service instead of the random number functions that libc provides.
The random service is the provider of the /dev/random and /dev/urandom system interfaces that provide random data. See random in the Utilities Reference.
Alternatively, you can access /dev/urandom via the QNX cryptography library by specifying urandom as the algorithm name when you request an RNG algorithm (using qcrypto_rng_request()). For more information, see “QNX Cryptography Library”.
