Requires the extension EGL_WL_bind_wayland_display, similar to eglBindWaylandDisplayWL.

Block and wait until for sync object is signaled or timeout is reached.

Parameters:

evas_gl	The current Evas_GL connection
sync	A valid sync object created by evasglCreateSync
timeout	A relative timeout in nanoseconds

Note:

Requires the extension EGL_KHR_reusable_sync, similarly to eglClientWaitSyncKHR.

Returns:

EVAS_GL_TIMEOUT_EXPIRED if the sync failed and timeout was reached, EVAS_GL_CONDITION_SATISFIED if the sync was signaled, or 0 in case of failure (in which case evas_gl_error_get() should return an error code)

Since (EFL) :

1.12

Create an EvasGLImage for the current context.

Common targets are:

• EVAS_GL_TEXTURE_2D:
  In case of EVAS_GL_TEXTURE_2D on EGL, the currently bound EGLContext will be used to create the image. The buffer argument must be a texture ID cast down to a void* pointer.
  Requires the EVAS_GL_image extension.

• EVAS_GL_NATIVE_SURFACE_TIZEN (Tizen platform only):
  Requires the EVAS_GL_TIZEN_image_native_surface extension.

Deprecated:

Note:

Please consider using evasglCreateImageForContext instead.

Create an EvasGLImage for a given context.

Parameters:

[in]	evas_gl	The current Evas GL object,
[in]	ctx	A context to create this image for,
[in]	target	One of EVAS_GL_TEXTURE_2D and EVAS_GL_NATIVE_SURFACE_TIZEN,
[in]	buffer	A pointer to a buffer, see below,
[in]	attrib_list	An array of key-value pairs terminated by 0 (see EVAS_GL_IMAGE_PRESERVED)

Common targets are:

• EVAS_GL_TEXTURE_2D:
  In case of EVAS_GL_TEXTURE_2D, the buffer argument must be a texture ID cast down to a void* pointer.
  Requires the EVAS_GL_image extension.

EvasGLImage *img = glapi->evasglCreateImageForContext
  (evasgl, ctx, EVAS_GL_TEXTURE_2D, (void*)(intptr_t)texture_id, NULL);

• EVAS_GL_NATIVE_SURFACE_TIZEN (Tizen platform only):
  Requires the EVAS_GL_TIZEN_image_native_surface extension.

Note:

Evas_GL_API must have version 2 or more.

Since :

2.3

Create a synchronization primitive which can be tested or waited upon.

Note:

Requires the extension EGL_KHR_fence_sync, similar to eglCreateSyncKHR.

Parameters:

evas_gl	The current Evas_GL connection
type	One of: EVAS_GL_SYNC_FENCE or EVAS_GL_SYNC_REUSABLE
attrib_list	Optional attributes list, terminated by EVAS_GL_NONE The supported attributes depend on the driver extensions, please refer to the EGL specifications for more information.

Returns:

A new sync object (EvasGLSync)

Since (EFL) :

1.12

Destroys an EvasGLImage. Destroy an image created by either evasglCreateImage or evasglCreateImageForContext.

Requires the EVAS_GL_image extension.

Note:

Unlike in pure EGL, the display pointer needs not be passed in, as Evas GL will use the same EGLDisplay as used in the create function.

Destroys a sync object created by evasglCreateSync.

Note:

Requires the extension EGL_KHR_fence_sync, similar to eglDestroySyncKHR.

Parameters:

evas_gl	The current Evas_GL connection
sync	A valid sync object created by evasglCreateSync

Returns:

EINA_TRUE in case of success, EINA_FALSE in case of failure (in which case evas_gl_error_get() should return an error code)

Since (EFL) :

1.12

Query a sync object for its properties.

Parameters:

evas_gl	The current Evas_GL connection
sync	A valid sync object created by evasglCreateSync
attribute	Which attribute to query, can be one of: EVAS_GL_SYNC_STATUS, EVAS_GL_SYNC_TYPE or EVAS_GL_SYNC_CONDITION
value	Return value or the query, see sync object.

Note:

Requires the extension EGL_KHR_fence_sync, similar to eglGetSyncAttribKHR.

Returns:

EINA_TRUE in case of success, or EINA_FALSE in case of failure (in which case evas_gl_error_get() should return an error code)

Since (EFL) :

1.12

Requires the extension EGL_WL_bind_wayland_display, similar to eglQueryWaylandBufferWL.

Signal a sync object, unlocking all threads waiting on it.

Parameters:

evas_gl	The current Evas_GL connection
sync	A valid sync object created by evasglCreateSync

Note:

Requires the extension EGL_KHR_reusable_sync or EGL_KHR_wait_sync, similarly to eglSignalSyncKHR.

Returns:

EINA_TRUE in case of success, or EINA_FALSE in case of failure (in which case evas_gl_error_get() should return an error code)

Since (EFL) :

1.12

Requires the extension EGL_WL_bind_wayland_display, similar to eglUnbindWaylandDisplayWL.

Wait on an EvasGLSync without blocking, see EGL_KHR_wait_sync for more information.

Parameters:

evas_gl	The current Evas_GL connection
sync	A valid sync object created by evasglCreateSync
flags	Must be 0

Note:

Requires the extension EGL_KHR_wait_sync, similar to eglWaitSyncKHR.

Returns:

EINA_TRUE in case of success, or EINA_FALSE in case of failure (in which case evas_gl_error_get() should return an error code)

Since (EFL) :

1.12

The current version number is EVAS_GL_API_VERSION (4). This should not be confused with the OpenGL-ES context version.
