Function Documentation

ptp_device_open()

int ptp_device_open	(	struct PtpRuntime *	r,
		struct PtpDeviceEntry *	entry )

ptpusb_device_list()

struct PtpDeviceEntry * ptpusb_device_list

(

struct PtpRuntime *

r

)

Get a linked list of USB or PTP Devices.

Returns

linked list of devices or NULL if no devices are connected (or OS error)
