This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGL2RenderingContext.getSyncParameter() method of the WebGL 2 API returns parameter information of a WebGLSync object.
Syntax
any gl.getSyncParameter(sync, pname);
Parameters
- sync
- A
WebGLSyncobject. pname- A
GLenumspecifying which information to return. Possible values:gl.OBJECT_TYPE: Returns aGLenumindicating the type of the sync object (alwaysgl.SYNC_FENCE).gl.SYNC_STATUS: Returns aGLenumindicating the status of the sync object (gl.SIGNALEDorgl.UNSIGNALED).gl.SYNC_CONDITION: Returns aGLenumindicating the sync objects' condition (alwaysgl.SYNC_GPU_COMMANDS_COMPLETE).gl.SYNC_FLAGS: Returns aGLenumindicating the flags with which the sync object was created (always 0 as no flags are supported).
Return value
Depends on the pname parameter, either a GLenum or a GLbitfield.
Examples
var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0); gl.getSyncParameter(sync, gl.SYNC_STATUS);
