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 WebGLSync object.

pname

A GLenum specifying which information to return. Possible values:

• gl.OBJECT_TYPE: Returns a GLenum indicating the type of the sync object (always gl.SYNC_FENCE).
• gl.SYNC_STATUS: Returns a GLenum indicating the status of the sync object (gl.SIGNALED or gl.UNSIGNALED).
• gl.SYNC_CONDITION: Returns a GLenum indicating the sync objects' condition (always gl.SYNC_GPU_COMMANDS_COMPLETE).
• gl.SYNC_FLAGS: Returns a GLenum indicating 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);
