	<para><function>glDeleteProgram</function> frees the memory and
	invalidates the name associated with the program object
	specified by <parameter>program.</parameter> This command
	effectively undoes the effects of a call to
	<citerefentry><refentrytitle>glCreateProgram</refentrytitle></citerefentry>.</para>

	<para>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
	<citerefentry><refentrytitle>glDeleteShader</refentrytitle></citerefentry>.
	A value of 0 for <parameter>program</parameter> will be silently
	ignored.</para>

	<para>To determine whether a program object has been flagged for
	deletion, call
	<citerefentry><refentrytitle>glGetProgramiv</refentrytitle></citerefentry>
	with arguments <parameter>program</parameter> and
	<constant>GL_DELETE_STATUS</constant>.</para>
