static int freerdp_connect_begin ( freerdp * instance )

static

Creates a new connection based on the settings found in the "instance" parameter It will use the callbacks registered on the structure to process the pre/post connect operations that the caller requires.

See also: struct rdp_freerdp in freerdp.h

Parameters

instance - pointer to a rdp_freerdp structure that contains base information to establish the connection. On return, this function will be initialized with the new connection's settings.

Returns: TRUE if successful. FALSE otherwise.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ freerdp_context_free()

void freerdp_context_free ( freerdp * instance )

Deallocator function for a rdp context. The function will deallocate the resources from the 'instance' parameter that were allocated from a call to freerdp_context_new(). If the ContextFree callback is set in the 'instance' parameter, it will be called before deallocation occurs.

Parameters

instance - Pointer to the rdp_freerdp structure that was initialized by a call to freerdp_context_new(). On return, the fields associated to the context are invalid.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ freerdp_context_new()

BOOL freerdp_context_new ( freerdp * instance )

Allocator function for a rdp context. The function will allocate a rdpRdp structure using rdp_new(), then copy its contents to the appropriate fields in the rdp_freerdp structure given in parameters. It will also initialize the 'context' field in the rdp_freerdp structure as needed. If the caller has set the ContextNew callback in the 'instance' parameter, it will be called at the end of the function.

Parameters

instance - Pointer to the rdp_freerdp structure that will be initialized with the new context.
