glDeleteSync delete a sync object

## C Specification

void `glDeleteSync` GLsync sync

## Parameters

sync

  The sync object to be deleted.

## Description

`glDeleteSync` deletes the sync object specified by sync. If the fence command corresponding to the specified sync object has completed, or if no glWaitSync or glClientWaitSync commands are blocking on sync, the object is deleted immediately. Otherwise, sync is flagged for deletion and will be deleted when it is no longer associated with any fence command and is no longer blocking any glWaitSync or glClientWaitSync command. In either case, after `glDeleteSync` returns, the name sync is invalid and can no longer be used to refer to the sync object.

`glDeleteSync` will silently ignore a sync value of zero.

## Notes

`glSync` is only supported if the GL version is 3.2 or greater, or if the `ARB_sync` extension is supported.

## Errors

`GL_INVALID_VALUE` is generated if sync is neither zero or the name of a sync object.
