glDeleteSync - OpenGL ES 3 Reference Pages

## Name

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.

## Errors

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