Delta Chat Core C-API
Modules
Here is a list of all modules:
 DC_MSGWith these constants the type of a message is defined
 DC_LPFlags for configuring IMAP and SMTP servers. These flags are optional and may be set together with the username, password etc. via dc_set_config() using the key "server_flags"
 DC_EVENTThese constants are used as events reported to the callback given to dc_context_new(). If you do not want to handle an event, it is always safe to return 0, so there is no need to add a "case" for every event
