| <!-- ================================ DESCRIPTION --> |
| |
| <refsect1 id="description"><title>Description</title> |
| <para> |
| This function is used to release OpenCL memory objects |
| that have been created from EGL resources. The EGL |
| objects are released by the OpenCL context associated |
| with <varname>command_queue</varname>. |
| </para> |
| |
| <para> |
| OpenCL memory objects created from EGL resources which have been acquired by OpenCL |
| must be released by OpenCL before they may be accessed by EGL or by EGL client APIs. |
| </para> |
| |
| <para> |
| Accessing a EGL resource while its corresponding |
| OpenCL memory object is acquired is in error |
| and will result in undefined behavior, including |
| but not limited to possible OpenCL errors, data |
| corruption, and program termination. |
