# eglInitialize

initialize an EGL display connection

## C Specification

`EGLBoolean eglInitialize(` | EGLDisplay display,
| EGLint * major,
| EGLint * minor`)`

## Parameters

`display`

  Specifies the EGL display connection to initialize.

`major`

  Returns the major version number of the EGL implementation. May be `NULL`.

`minor`

  Returns the minor version number of the EGL implementation. May be `NULL`.

## Description

`eglInitialize` initialized the EGL display connection obtained with eglGetDisplay. Initializing an already initialized EGL display connection has no effect besides returning the version numbers.

`major` and `minor` do not return values if they are specified as `NULL`.

Use eglTerminate to release resources associated with an EGL display connection.

## Errors

`EGL_FALSE` is returned if `eglInitialize` fails, `EGL_TRUE` otherwise. `major` and `minor` are not modified when `EGL_FALSE` is returned.

`EGL_BAD_DISPLAY` is generated if `display` is not an EGL display connection.

`EGL_NOT_INITIALIZED` is generated if `display` cannot be initialized.
