<h2>Description</h2>
<p><code class="function">glDeleteProgram</code> frees the memory and
invalidates the name associated with the program object
specified by <em class="parameter"><code>program.</code></em> This command
effectively undoes the effects of a call to
<a class="citerefentry" href="glCreateProgram.xhtml"><span class="citerefentry"><span class="refentrytitle">glCreateProgram</span></span></a>.</p>
<p>If a program object is in use as part of current rendering
state, it will be flagged for deletion, but it will not be
deleted until it is no longer part of current state for any
rendering context. If a program object to be deleted has shader
objects attached to it, those shader objects will be
automatically detached but not deleted unless they have already
been flagged for deletion by a previous call to
<a class="citerefentry" href="glDeleteShader.xhtml"><span class="citerefentry"><span class="refentrytitle">glDeleteShader</span></span></a>.
A value of 0 for <em class="parameter"><code>program</code></em> will be silently
ignored.</p>
<p>To determine whether a program object has been flagged for
deletion, call
<a class="citerefentry" href="glGetProgram.xhtml"><span class="citerefentry"><span class="refentrytitle">glGetProgram</span></span></a>
with arguments <em class="parameter"><code>program</code></em> and
<code class="constant">GL_DELETE_STATUS</code>.</p>
