<para>
<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.

<refsect1 xml:id="errors"><title>Errors</title>
<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).
