=item get_courseinfo_hash( $cnum, $cdom, $home ) |
|
|
|
get_courseinfo_hash() is used to retrieve course information from the db |
|
file: nohist_courseids.db for a course for which the current server is *not* |
|
the home server. |
|
|
|
A hash of a hash will be retrieved. The outer hash contains a single key -- |
|
courseID -- for the course for which the data are being requested. |
|
The contents of the inner hash, for that single item in the outer hash |
|
are returned (and cached in memcache for 10 minutes). |
|
|
|
=item get_dom ( $userinput ) |
|
|
|
get_dom() will retrieve domain configuration information from a GDBM file |
|
in /home/httpd/lonUsers/$dom on the primary library server in a domain. |
|
The single argument passed is the string: $cmd:$udom:$namespace:$what |
|
where $cmd is the command historically passed to lond - i.e., getdom |
|
or egetdom, $udom is the domain, $namespace is the name of the GDBM file |
|
(encconfig or configuration), and $what is a string containing names of |
|
items to retrieve from the db file (each item name is escaped and separated |
|
from the next item name with an ampersand). The return value is either: |
|
error: followed by an error message, or a string containing the value (escaped) |
|
for each item, again separated from the next item with an ampersand. |
