## Function Documentation

## ◆ data_dump()

void data_dump | ( | FILE * | f,
|  | void * | buf,
|  | uint32_t | n )

This dumps out a number of bytes to a textual, hexadecimal dump.

Parameters

  f | the file to dump to (e.g. stdout or stderr)
  buf | a pointer to the buffer containing the bytes to be dumped out in hex
  n | the number of bytes to dump from this buffer

## ◆ data_dump_ascii()

void data_dump_ascii | ( | FILE * | f,
|  | void * | buf,
|  | uint32_t | n,
|  | uint32_t | dump_boundry )

This dumps out a number of bytes to a textual, hexadecimal dump, and also prints out the string ASCII representation for each line of bytes. It will also print the memory address offset from a certain boundry.

Parameters

  f | the file to dump to (e.g. stdout or stderr)
  buf | a pointer to the buffer containing the bytes to be dumped out in hex
  n | the number of bytes to dump from this buffer
  dump_boundry | the address offset to start at (usually 0)

## ◆ device_unknown()

void device_unknown | ( | const int | dev_number,
|  | const int | id_vendor,
|  | const int | id_product )

This prints to stdout info about device being UNKNOWN, its ids, and libmtp's version number.

Parameters

  dev_number | the device number
  id_vendor | vendor ID from the usb_device_desc struct
  id_product | product ID from the usb_device_desc struct
