   5 ## Overview
   6
   7 Since Linux 3.17 there is a system call `getrandom()`. This was added to glibc 2.25.
   8
   9 This library can be used with `LD_PRELOAD` if you're using Linux 3.16 or earlier and need to run an application which requires `getrandom()`.

  11 See [LWN's The long road to getrandom() in glibc](https://lwn.net/Articles/711013/) for more information.
