Set core affinity for thread in zig

Question

What is the suggested way to set core affinity for thread in zig programming language? Can't find anything similar in the docs below:

• https://ziglang.org/documentation/master/#Top-Level-Doc-Comments
• https://ziglang.org/documentation/master/std/#std?thread

Answer 1

Setting core affinity isn't currently implemented in the standard library.

Since zig makes it very easy to bind to C functions, you can just use a @cImport() to load the platform-specific C headers containing the functions you would like to use, e.g. sched.h for sched_setaffinity(2), pthread.h for pthread_setaffinity_np(3) on Linux or winbase.h for SetThreadAffinityMask, SetProcessAffinityMask on Windows.

@cImport() will then give you back a scope that contains all these functions as if they were defined in Zig: https://ziglang.org/documentation/0.6.0/#Import-from-C-Header-File
