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)
