<para>In order to create an executable, 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 permissible to attach multiple shader objects of the same
|
|
type because each may contain a portion of the complete shader.
|
|
It is also 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>
