eglQueryAPI — Query the current rendering API

C Specification

EGLenum eglQueryAPI( void);  


eglQueryAPI returns the value of the current rendering API for EGL in the thread it is called from. The current rendering API is set by eglBindAPI, and affects the behavior of other EGL commands.

The value returned will be one of the valid api parameters to eglBindAPI, or EGL_NONE.


eglQueryAPI is supported only if the EGL version is 1.2 or greater.

The initial value of the current rendering API is EGL_OPENGL_ES_API unless OpenGL ES is not supported by an implementation, in which case the initial value is EGL_NONE (however, EGL_NONE is not a valid api parameter to eglQueryAPI).

The current rendering API can be changed by calling eglBindAPI.
