            <function>eglGetCurrentDisplay</function> returns the current
            <acronym>EGL</acronym> display connection for the current
            <acronym>EGL</acronym> rendering context, as specified by
            <citerefentry><refentrytitle>eglMakeCurrent</refentrytitle></citerefentry>.
            If no context is current, <constant>EGL_NO_DISPLAY</constant> is returned.

        <para>
            Passing <constant>EGL_NO_DISPLAY</constant> to any command
            taking an <type>EGLDisplay</type> parameter will generate either
            an <constant>EGL_BAD_DISPLAY</constant> error if the EGL
            implementation validates <type>EGLDisplay</type> 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
            <function>eglQueryString</function> will accept an
            <type>EGLDisplay</type> parameter of
            <constant>EGL_NO_DISPLAY</constant> when querying the client
            extension string (see section 3.3 of the EGL 1.5 Specification).
