Detailed Description

This file contains most generic functions and switches between different protocols depending on the device type that has been connected.

Function Documentation

int _file_size	(	njb_t *	njb,
		const char *	path,
		u_int64_t *	size
	)

This is a helper function for retrieveing the file size for a file on the host system.

Referenced by NJB_Send_File(), NJB_Send_Firmware(), and NJB_Send_Track().

int _file_time	(	njb_t *	njb,
		const char *	path,
		time_t *	ts
	)

This is a helper function to retrieve the time stamp for a file on the host system.

int NJB_Handshake

(

njb_t *

njb

)

This function "handshakes" a previously opened and captured device represented by a njb_t object. This basically means some basic "how do you do" calls are made, and the njb_id_t property of the njb_t object gets filled in properly.

Parameters

njb	a pointer to the njb_t object to perform the handshake on

Returns

0 on success, -1 on failure
