<p>The Change Library List (QLICHGLL) API changes the current library, the two
|
||
|
|
product libraries, and the user part of the current thread's library list.
|
||
|
|
This API provides the only way to change the two product libraries in the library list.
|
||
|
|
The only other way to change the product libraries is using the Create Command (CRTCMD)
|
||
|
|
or the Create Menu (CRTMNU) command.</p>
|
||
|
|
|
||
|
|
<p>When the initial thread's library list is changed, each library added to the
|
||
|
|
list may be locked with a shared-read lock. The value of the QLIBLCKLVL system
|
||
|
|
value determines whether libraries in the library list are locked. If a library
|
||
|
|
is being removed from the initial thread's library list, and it was locked when
|
||
|
|
it was added to the library list, the shared-read lock is released. When a
|
||
|
|
secondary thread's library list is changed, libraries added to the library list
|
||
|
|
are not locked.</p>
|
||
|
|
|
||
|
|
<p>Authority to the library is checked whenever a library name is specified on
|
||
|
|
one of the required parameters.</p>
|
||
|
|
|
||
|
|
<p>You may want to save the current thread's library list before changing it.
|
||
|
|
The QWCRTVCA API can be used to retrieve the current thread's library list. The
|
||
|
|
Retrieve Job Information (QUSRJOBI) API can be used to retrieve the initial
|
||
|
|
thread's library list, when the current thread is not the initial thread. You
|
||
|
|
can then change the library list back to its original value by using the
|
||
|
|
QLICHGLL API with the libraries saved from the QUSRJOBI or QWCRTVCA API.</p>
