=item get_course_users |
|
|
|
Retrieves usernames:domains for users in the specified course |
|
with specific role(s), and access status. |
|
|
|
Incoming parameters: |
|
1. course domain |
|
2. course number |
|
3. access status: users must have - either active, |
|
previous, future, or all. |
|
4. reference to array of permissible roles |
|
5. reference to array of section restrictions (optional) |
|
6. reference to results object (hash of hashes). |
|
7. reference to optional userdata hash |
|
Keys of top level hash are roles. |
|
Keys of inner hashes are username:domain, with |
|
values set to access type. |
|
Optional userdata hash returns an array with arguments in the |
|
same order as loncoursedata::get_classlist() for student data. |
|
|
|
Entries for end, start, section and status are blank because |
|
of the possibility of multiple values for non-student roles. |
