eglQueryAPI
Query the current rendering API
C Specification
EGLenum eglQueryAPI(
| void); |
Description
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.
Notes
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.
