GW OBEX Error Codes
The error codes returned by many of the functions refer either to an OBEX Protocol error or to a GW OBEX error. If the error code is less that 256, it refers to an OBEX error, othervice it refers to a GW_OBEX_ERROR_* error.

Functions
Functions for connecting and disconnecting
With these functions you can create and and disconnect connections. You can either connect using a filename (e.g. "/dev/rfcomm0") or using a file descriptor (e.g. a RFCOMM socket).

xfer

Pointer returned by gw_obex_put_async or gw_obex_get_async

unsigned char* gw_obex_xfer_object_apparam	(	GwObexXfer *	xfer,
		size_t *	apparam_size
	)

Get the contents of the application parameters header

Parameters:

	xfer	Pointer returned by gw_obex_put_async or gw_obex_get_async
	apparam_size	Return value for the size of the application parameters header.

Returns:

The pointer to the buffer that hold the contents.

gboolean gw_obex_xfer_object_done

(

GwObexXfer *

xfer

)

Returns if a transfer is already done

Parameters:

xfer

Pointer returned by gw_obex_put_async or gw_obex_get_async

Returns:

whether the current transfer is done

gint gw_obex_xfer_object_size

(

GwObexXfer *

xfer

)

Get the size of the object being transfered

Parameters:

xfer

Pointer returned by gw_obex_put_async or gw_obex_get_async

Returns:

The size or GW_OBEX_UNKNOWN_LENGTH if it is not known.

time_t gw_obex_xfer_object_time

(

GwObexXfer *

xfer

)

Get the last modification time of the object being transfered

Parameters:

xfer

Pointer returned by gw_obex_put_async or gw_obex_get_async

Returns:

The modification time or -1 if it is not known.

gboolean gw_obex_xfer_read	(	GwObexXfer *	xfer,
		char *	buf,
		gint	buf_size,
		gint *	bytes_read,
		gint *	error
	)

Read data from a transfer

The function will report EOF by returning success with zero bytes read.

Parameters:

	xfer	Pointer returned by gw_obex_put_async or gw_obex_get_async
	buf	Buffer where the data should be stored
	buf_size	Size of the buffer
	bytes_read	Return value for the number of bytes that were read
	error	Place to store error code on failure (NULL if not interested)

Returns:

TRUE on success, FALSE on failure

void gw_obex_xfer_set_blocking	(	GwObexXfer *	xfer,
		gboolean	block
	)

Set blocking behaviour for a GwObexXfer object when calling xfer_read and xfer_write

When blocking is enabled xfer_read will return only after it has been able to read some data (i.e. GW_OBEX_ERROR_NO_DATA will not be returned). For xfer_write blocking guarantees that *some* data will be written.

Parameters:

	xfer	Pointer returned by gw_obex_put_async or gw_obex_get_async
	block	TRUE to enable blocking behaviour

void gw_obex_xfer_set_callback	(	GwObexXfer *	xfer,
		gw_obex_xfer_cb_t	cb,
		gpointer	user_data
	)

Set a callback function for a GwObexXfer object The callback function will be called in the following situations:

• Data can be written (i.e. xfer_write will succeed)
• Data can be read (i.e. xfer_read will succees)
• An error ocured
• The transfer is finished

Parameters:

	xfer	Pointer returned by gw_obex_put_async or gw_obex_get_async
	cb	Pointer to the callback function
	user_data	Optional user data which will be passed to the callback function

Returns:

a new GwObexXfer object on success, NULL on failure

gboolean gw_obex_xfer_write	(	GwObexXfer *	xfer,
		const char *	buf,
		gint	buf_size,
		gint *	bytes_written,
		gint *	error
	)

Supply more data to a transfer

Parameters:

	xfer	Pointer returned by gw_obex_put_async or gw_obex_get_async
	buf	Buffer containing the data
	buf_size	Size of the buffer
	bytes_written	Return value for the number of bytes that were written
	error	Place to store error code on failure (NULL if not interested)

Returns:

TRUE on success, FALSE on failure
