<para>
<function>eglInitialize</function> initialized the EGL display
connection obtained with
<citerefentry><refentrytitle>eglGetDisplay</refentrytitle></citerefentry>.
Initializing an already initialized EGL display connection has no
effect besides returning the version numbers.
</para>
<para>
<parameter>major</parameter> and <parameter>minor</parameter>
do not return values if they are specified as <constant>NULL</constant>.
</para>
<para>
Use <citerefentry><refentrytitle>eglTerminate</refentrytitle></citerefentry>
to release resources associated with an EGL display connection.
</para>

<refsect1 xml:id="errors"><title>Errors</title>
<para>
<constant>EGL_FALSE</constant> is returned if
<function>eglInitialize</function> fails,
<constant>EGL_TRUE</constant> otherwise.
<parameter>major</parameter> and <parameter>minor</parameter> are not
modified when <constant>EGL_FALSE</constant> is returned.
</para>
<para>
<constant>EGL_BAD_DISPLAY</constant> is generated if
<parameter>display</parameter> is not an EGL display connection.
</para>
<para>
<constant>EGL_NOT_INITIALIZED</constant> is generated if
<parameter>display</parameter> cannot be initialized.
