* TEglEndpointWrap is a simple class that presents all of the EGL endpoint
|
|
sl@0
|
36 |
* extension functions without the user needing to perform an eglGetProcAddress()
|
|
sl@0
|
37 |
* to obtain the function pointer. Each endpoint member function takes the same
|
|
sl@0
|
38 |
* arguments as the EGL functions and returns the same types. After before first
|
|
sl@0
|
39 |
* use, you should check the Error() function to ensure that all function pointers
|
|
sl@0
|
40 |
* were resolved. Trying to use one of the endpoint functions in the event of a
|
|
sl@0
|
41 |
* construction error will result in a panic.
