<refsect1 xml:id="description"><title>Description</title>
<para>In order to create a complete shader program, there must be a way to
specify the list of things that will be linked together. Program
objects provide this mechanism. Shaders that are to be linked
together in a program object must first be attached to that
program object. <function>glAttachShader</function> attaches the
shader object specified by <parameter>shader</parameter> to the
program object specified by <parameter>program</parameter>. This
indicates that <parameter>shader</parameter> will be included in
link operations that will be performed on
<parameter>program</parameter>.</para>
<para>All operations that can be performed on a shader object
are valid whether or not the shader object is attached to a
program object. It is permissible to attach a shader object to a
program object before source code has been loaded into the
shader object or before the shader object has been compiled. It
is not permissible to attach multiple shader objects of the same
type.
It is permissible to attach a shader object to more than
one program object. If a shader object is deleted while it is
attached to a program object, it will be flagged for deletion,
and deletion will not occur until
<citerefentry><refentrytitle>glDetachShader</refentrytitle></citerefentry>
is called to detach it from all program objects to which it is
attached.</para>
