Description

GetNewsgroupList is an overloaded procedure in TIdNNTP that retrieves a list of valid newsgroups on the NNTP server. GetNewsgroupList sends the NNTP LIST command to retrieve newsgroup information returned in the NNTP server response.

The overloaded GetNewsgroupList procedures provide for storing server response lines in the AStream argument. Newsgroup information is stored in AStream using the Capture method in IOHandler for the NNTP client.

Newsgroup information returned in an NNTP server response may consist of multiple lines of text in the form:

  groupname last first p

Tokens in the response line have the following meanings:

Token	Meaning
groupname	newsgroup name.
last	number of the last known article currently in the newsgroup.
first	number of the first article currently in the newsgroup.
p	posting status for the newsgroup. ('y'=allowed, 'n'=prohibited)
