source: functions.c @ 1c6c4d3

barnowl_perlaimdebianowlrelease-1.10release-1.4release-1.5release-1.6release-1.7release-1.8release-1.9
Last change on this file since 1c6c4d3 was 1c6c4d3, checked in by Erik Nygren <nygren@mit.edu>, 22 years ago
Added owl_sprintf which returns the formatted string, or NULL. The caller must free this string. This will allocate enough memory and thus avoid potential some buffer overrun situations. Started fixing some potential buffer overrun situations. Simple implementation of 'zwrite -m' (doesn't yet log an outgoing message as having been sent.) The "Not logged in or subscribing to messages" error now includes the name of the recipient.
