2003-2014 The Khronos Group Inc. eglGetError 3G eglGetError return error information EGLint eglGetError eglGetError returns the error of the last called EGL function in the current thread. Initially, the error is set to EGL_SUCCESS. When an EGL function could potentially generate several different errors (for example, when passed both a bad attribute name, and a bad attribute value for a legal attribute name), the implementation may choose to generate any one of the applicable errors. The following errors are currently defined: EGL_SUCCESS The last function succeeded without error. EGL_NOT_INITIALIZED EGL is not initialized, or could not be initialized, for the specified EGL display connection. EGL_BAD_ACCESS EGL cannot access a requested resource (for example a context is bound in another thread). EGL_BAD_ALLOC EGL failed to allocate resources for the requested operation. EGL_BAD_ATTRIBUTE An unrecognized attribute or attribute value was passed in the attribute list. EGL_BAD_CONTEXT An EGLContext argument does not name a valid EGL rendering context. EGL_BAD_CONFIG An EGLConfig argument does not name a valid EGL frame buffer configuration. EGL_BAD_CURRENT_SURFACE The current surface of the calling thread is a window, pixel buffer or pixmap that is no longer valid. EGL_BAD_DISPLAY An EGLDisplay argument does not name a valid EGL display connection. EGL_BAD_SURFACE An EGLSurface argument does not name a valid surface (window, pixel buffer or pixmap) configured for GL rendering. EGL_BAD_MATCH Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface). EGL_BAD_PARAMETER One or more argument values are invalid. EGL_BAD_NATIVE_PIXMAP A NativePixmapType argument does not refer to a valid native pixmap. EGL_BAD_NATIVE_WINDOW A NativeWindowType argument does not refer to a valid native window. EGL_CONTEXT_LOST A power management event has occurred. The application must destroy all contexts and reinitialise OpenGL ES state and objects to continue rendering. A call to eglGetError sets the error to EGL_SUCCESS.
