Graphics.Caramia.Sync

Contents

Description

Synchronization primitives.

This module implements fence synchronization objects. They can be used to check when a GPU operation has been done.

At the moment, the only place where these objects are useful in Caramia is unsynchronized buffer mapping.

Operations in this module require GL_ARB_sync extension or OpenGL 3.2.

Synopsis

Operations

Create a fence.

Arguments

:: MonadIO m
=> Int	Number of microseconds to wait.
-> Fence
-> m Bool	`True` if the fence was signalled, `False` if waiting timed out.

Waits for a fence to signal.

IMPORTANT: this is not interruptible by asynchronous exceptions.

Checks if a fence has been signalled.

 isFenceSignalled = waitFence 0
