Random number generation
QNX SDP8.0QNX OS System Security GuideAPIConfiguration
For best security, QNX recommends you use the QNX OS random service for random number generation 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
