Detailed Description

The IM service provides one-on-one communication between users.

Messages sent over conversations may relay different types of information, in a variety of formats. The basic feature-set provides plain-text chat with typing notification. More complex features may be negotiated transparently by setting the IM Client Type for a conversation, or for the service as a whole.

Enumeration Type Documentation

◆ mwConversationState

See also
mwConversation_getState
Enumerator
mwConversation_CLOSED 

conversation is not open

mwConversation_PENDING 

conversation is opening

mwConversation_OPEN 

conversation is open

mwConversation_UNKNOWN 

unknown state

◆ mwImClientType

Enumerator
mwImClient_PLAIN 

text, typing

mwImClient_NOTESBUDDY 

adds html, subject, mime

mwImClient_PRECONF 

pre-conference, legacy

mwImClient_UNKNOWN 

trouble determining type

◆ mwImSendType

Types of supported messages.

When a conversation is created, the least common denominator of features between either side of the conversation (based on what features are available in the IM service itself) becomes the set of supported features for that conversation. At any point, the feature set for the service may change, without affecting any existing conversations.

Function Documentation

◆ mwConversation_close()

void mwConversation_close ( struct mwConversation conv,
guint32  err 
)

close a conversation.

If the conversation was not already closed, mwServiceImHandler::conversation_closed will be triggered

◆ mwConversation_free()

void mwConversation_free ( struct mwConversation conv)

close and destroy the conversation and its backing channel, and call the optional client data cleanup function

◆ mwConversation_getClientData()

gpointer mwConversation_getClientData ( struct mwConversation conv)

Reference associated client data.

See also
mwConversation_setClientData
mwConversation_removeClientData

◆ mwConversation_getClientType()

enum mwImClientType mwConversation_getClientType ( struct mwConversation conv)

◆ mwConversation_getService()

struct mwServiceIm* mwConversation_getService ( struct mwConversation conv)
Returns
owning service for a conversation

◆ mwConversation_getState()

enum mwConversationState mwConversation_getState ( struct mwConversation conv)

◆ mwConversation_getTarget()

struct mwIdBlock* mwConversation_getTarget ( struct mwConversation conv)

ID for conversation partner.

◆ mwConversation_getTargetInfo()

struct mwLoginInfo* mwConversation_getTargetInfo ( struct mwConversation conv)

login information for conversation partner.

returns NULL if conversation is not OPEN

◆ mwConversation_isEncrypted()

gboolean mwConversation_isEncrypted ( struct mwConversation conv)

determine whether outgoing messages are being encrypted

◆ mwConversation_open()

void mwConversation_open ( struct mwConversation conv)

attempt to open a conversation.

If the conversation was not already open and it is accepted, mwServiceImHandler::conversation_opened will be triggered. Upon failure, mwServiceImHandler::conversation_closed will be triggered

◆ mwConversation_removeClientData()

void mwConversation_removeClientData ( struct mwConversation conv)

Remove any associated client data, calling the optional cleanup function if one was provided.

See also
mwConversation_setClientData
mwConversation_getClientData

◆ mwConversation_send()

int mwConversation_send ( struct mwConversation conv,
enum mwImSendType  type,
gconstpointer  send 
)

send a message over an open conversation

◆ mwConversation_setClientData()

void mwConversation_setClientData ( struct mwConversation conv,
gpointer  data,
GDestroyNotify  clean 
)

Associates client data with a conversation.

If there is existing data, it will not have its cleanup function called.

mwConversation_getClientData
mwConversation_removeClientData

◆ mwConversation_setEncrypted()

void mwConversation_setEncrypted ( struct mwConversation conv,
gboolean  useCipher 
)

set whether outgoing messages should be encrypted using the negotiated cipher, if any

◆ mwConversation_supports()

gboolean mwConversation_supports ( struct mwConversation conv,
enum mwImSendType  type 
)

determine whether a conversation supports the given message type

◆ mwServiceIm_findConversation()

struct mwConversation* mwServiceIm_findConversation ( struct mwServiceIm srvc,
struct mwIdBlock target 
)

reference an existing conversation to target

◆ mwServiceIm_getClientType()

enum mwImClientType mwServiceIm_getClientType ( struct mwServiceIm srvc)

◆ mwServiceIm_getConversation()

struct mwConversation* mwServiceIm_getConversation ( struct mwServiceIm srvc,
struct mwIdBlock target 
)

reference an existing conversation to target, or create a new conversation to target if one does not already exist

◆ mwServiceIm_getHandler()

struct mwImHandler* mwServiceIm_getHandler ( struct mwServiceIm srvc)

◆ mwServiceIm_new()

struct mwServiceIm* mwServiceIm_new ( struct mwSession session,
struct mwImHandler handler 
)

◆ mwServiceIm_setClientType()

void mwServiceIm_setClientType ( struct mwServiceIm srvc,
enum mwImClientType  type 
)

Set the default client type for the service.

Newly created conversations will attempt to meet this level of functionality first.

Parameters
srvcthe IM service
typethe send type to enable/disable

◆ mwServiceIm_supports()

gboolean mwServiceIm_supports ( struct mwServiceIm srvc,
enum mwImSendType  type 
)

determine if the conversations created from this service will support a given send type
