## Functions

void | data_dump_ascii (FILE *f, void *buf, size_t n, size_t dump_boundry)
## Variables
int | __sub_depth

## Detailed Description

This file contain some general I/O helper routines, related to the operating system and debug output.

## Function Documentation

void data_dump | ( | FILE * | f,
|  | void * | buf,
|  | size_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

void data_dump_ascii | ( | FILE * | f,
|  | void * | buf,
|  | size_t | n,
|  | size_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)
