## 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.

Referenced by NJB_Send_File().

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
