<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"><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"><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="glGetProgramiv"><span class="citerefentry"><span class="refentrytitle">glGetProgramiv</span></span></a>

with arguments <em class="parameter"><code>program</code></em> and

<code class="constant">GL_DELETE_STATUS</code>.</p>

<h2>Errors</h2>

<p><code class="constant">GL_INVALID_VALUE</code> is generated if

<em class="parameter"><code>program</code></em> is not a value generated by

OpenGL.</p>
