<h2>Description</h2>
<p>
<code class="function">eglGetError</code> returns the error of the last
called <abbr class="acronym">EGL</abbr> function in the current thread.
Initially, the error is set to <code class="constant">EGL_SUCCESS</code>.
</p>
<p>
When an EGL function could potentially generate several
different errors (for example, when passed both a bad attribute
name, and a bad attribute value for a legal attribute name), the
implementation may choose to generate any one of the applicable
errors.
