<p>The <strong>qsysetreuid()</strong> function sets the real and effective user

IDs to the values specified by <em>ruid</em> and <em>euid</em>.</p>
|

|

|
|
<p>A thread with *ALLOBJ special authority can set either ID to any value.</p>
|

|
<p>A thread without *ALLOBJ special authority can only set the effective user

ID if the <em>euid</em> argument is equal to the real, effective, or saved user
|

|
|
ID.</p>
|

<p>Job scoped locks with a lock state of *SHRRD are held on the user profiles
