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 aGLenum
indicating the type of the sync object (alwaysgl.SYNC_FENCE
).gl.SYNC_STATUS
: Returns aGLenum
indicating the status of the sync object (gl.SIGNALED
orgl.UNSIGNALED
).gl.SYNC_CONDITION
: Returns aGLenum
indicating the sync objects' condition (alwaysgl.SYNC_GPU_COMMANDS_COMPLETE
).gl.SYNC_FLAGS
: Returns aGLenum
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);
