<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>.
