|
|
|
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. |
