eglGetCurrentDisplay — return the display for the current EGL rendering context
EGLDisplay eglGetCurrentDisplay(
|
void) ; |
eglGetCurrentDisplay
returns the current
EGL display connection for the current
EGL rendering context, as specified by
eglMakeCurrent.
If no context is current, EGL_NO_DISPLAY
is returned.
Passing EGL_NO_DISPLAY
to any command
taking an EGLDisplay parameter will generate either
an EGL_BAD_DISPLAY
error if the EGL
implementation validates EGLDisplay handles, or
undefined behavior as described at the end of section 3.1 of the
EGL 1.5 Specification. The only exception to this rule is that
eglQueryString
will accept an
EGLDisplay parameter of
EGL_NO_DISPLAY
when querying the client
extension string (see section 3.3 of the EGL 1.5 Specification).
