EGL-Display

Implements the binding of a native os-specific graphics display to OpenGL / OpenGLES. The implementation uses the EGL API which adapts OpenGL to the native windowing system.

Types

opengl_display_t

typedef struct opengl_display_t opengl_display_t

Type which tags the native implementation of an OpenGL capable display.

struct egldisplay_t

Export egldisplay_t into global namespace.

Functions

Summary

test
unittest_platform_opengl_egl_egldisplay	Test egldisplay_t functionality.

test

unittest_platform_opengl_egl_egldisplay

int unittest_platform_opengl_egl_egldisplay( void )

Test egldisplay_t functionality.

egldisplay_t

typedef struct opengl_display_t * egldisplay_t

Wrapper of a native display type. Adds additional information used by OpenGL / EGL.

Summary

lifetime
egldisplay_FREE	Static initializer.
initdefault_egldisplay	Initializes egldisp with the default display connection.
initx11_egldisplay	Initializes egldisp with x11disp.
free_egldisplay	Frees all associated resources with a display.

lifetime

egldisplay_FREE

#define egldisplay_FREE 0

Static initializer.

initdefault_egldisplay

int initdefault_egldisplay( /*out*/egldisplay_t * egldisp )

Initializes egldisp with the default display connection. Returns EINVAL if there is no default display connection or EALLOC if the egl specific part could not be initialized.

initx11_egldisplay

int initx11_egldisplay( /*out*/egldisplay_t * egldisp,
struct x11display_t * x11disp )

Initializes egldisp with x11disp. Returns EINVAL if x11disp is not initialized or invalid or EALLOC if the egl specific part could not be initialized. Do not free x11disp as long as egldisp is not freed.

free_egldisplay

int free_egldisplay( egldisplay_t * egldisp )

Frees all associated resources with a display. If one or more threads has a current context and surface these resources are marked for deletion.
