<p>If the thread has *ALLOBJ special authority, <strong>qsysetuid()</strong>
|
|
sets the real, effective, and saved user ID to <em>uid</em>.</p>
|
|
|
|
<p>If the thread does not have *ALLOBJ special authority, but <em>uid</em> is
|
|
equal to the real, effective or saved user ID, <strong>qsysetuid()</strong>
|
|
sets the effective user ID to <em>uid</em>. The real and saved user IDs remain
|
|
unchanged.</p>
|
|
|
|
<p>Job scoped locks with a lock state of *SHRRD are held on the user profiles
|
|
associated with the real user ID, effective user ID, saved user ID, real group
|
|
ID, effective group ID, saved group ID, and all of the supplemental groups.</p>
