=item &get_classlist(); |
|
|
|
Retrieve the classist of a given class or of the current class. Student |
|
information is returned from the classlist.db file and, if needed, |
|
from the students environment. |
|
|
|
Optional arguments are $cid, $cdom, and $cnum (course id, course domain, |
|
and course number, respectively). Any omitted arguments will be taken |
|
from the current environment ($ENV{'request.course.id'}, |
|
$ENV{'course.'.$cid.'.domain'}, and $ENV{'course.'.$cid.'.num'}). |
|
|
|
Returns a reference to a hash which contains: |
|
keys '$sname:$sdom' |
|
values [$end,$start,$id,$section,$fullname] |
