static

Call mouse callback after a mouse event.

Definition at line 156 of file uSynergy.c.

◆ sSendReply()

static uSynergyBool sSendReply ( uSynergyContext * context )

static

Send reply packet.

Definition at line 131 of file uSynergy.c.

◆ sSetDisconnected()

static void sSetDisconnected ( uSynergyContext * context )

static

Mark context as being disconnected.

Definition at line 462 of file uSynergy.c.

◆ sTrace()

static void sTrace	(	uSynergyContext *	context,
		const char *	text
	)

static

Trace text to client.

Definition at line 69 of file uSynergy.c.

◆ sUpdateContext()

static void sUpdateContext ( uSynergyContext * context )

static

Update a connected context.

Definition at line 476 of file uSynergy.c.

◆ uSynergyInit()

void uSynergyInit ( uSynergyContext * context )

Initialize uSynergy context.

This function initializes context for use. Call this function directly after creating the context, before filling in any configuration data in it. Not calling this function will cause undefined behavior.

Parameters

context Context to be initialized

Definition at line 570 of file uSynergy.c.

◆ uSynergySendClipboard()

void uSynergySendClipboard	(	uSynergyContext *	context,
		const char *	text
	)

Send clipboard data.

This function sets new clipboard data and sends it to the server. Use this function if your client cuts or copies data onto the clipboard that it needs to share with the server.

Currently there is only support for plaintext, but HTML and image data could be supported with some effort.

Parameters

context	Context to send clipboard data to
text	Text to set to the clipboard

Definition at line 603 of file uSynergy.c.

◆ uSynergyUpdate()

void uSynergyUpdate ( uSynergyContext * context )

Update uSynergy.

This function updates uSynergy and does the bulk of the work. It does connection management, receiving data, reconnecting after errors or timeouts and so on. It assumes that networking operations are blocking and it can suspend the current thread if it needs to wait. It is best practice to call uSynergyUpdate from a background thread so it is responsive.

Because uSynergy relies mostly on blocking calls it will mostly stay in thread sleep state waiting for system mutexes and won't eat much memory.

uSynergyUpdate doesn't do any memory allocations or have any side effects beyond those of the callbacks it calls.

Parameters

context Context to be updated
