    13 // Description:

    14 // Test case code for checking current behaviour of graphics_openglesheaders

    15 // The purpose of this source code is to thrown an error during compilation

    16 // if the GLES/egl.h header does not re-direct to the system-wide EGL/egl.h

    17 // The use of GLES/egl.h is a legacy, and kept to ease the transition of

    18 // applications to using EGL/egl.h instead.

    19 // This code must be compiled without the legacy setting

    20 // __OPENGLESHEADERS_LEGACY_EGL_1_1 to ensure that GLES/egl.h re-directs

    21 // to the system-wide EGL/egl.h

    22 //
