Detailed Description

uint32_t av_get_random_seed ( void  )

Get a seed to use in conjunction with random functions.

This function tries to provide a good seed at a best effort bases. Its possible to call this function multiple times if more bits are needed. It can be quite slow, which is why it should only be used as seed for a faster PRNG. The quality of the seed depends on the platform.
