#2366 closed enhancement (wontfix)

Create a Public API for the Atomic Operations

Description

Ticket #2364 regarded use of a pthread mutex in three graphics driver as basically an atomic flag to ensure only one open() was active at a time. This created an unnecessary dependency on the POSIX API being enabled. I changed the code to use score Atomic flags.

This highlighted the need for a public Atomic API.

The existing tests could be converted to the public API, a macro wrapper written for Classic API Atomics, and documentation added. This may be enough to be a small GSOC project.

Why not simply use C11/C++11 atomic operations?

Milestone: 5.0 → 4.12.0
Version: 4.11 → 4.12

Should the API in 'sys/locks.h' be used?

Resolution: → wontfix
Status: new → closed

Since C11 or C++11 is now the default in GCC users can simply use the standard atomic operations.
