Function Documentation

int bless_buffer_copy	(	bless_buffer_t *	src,
		off_t	src_offset,
		bless_buffer_t *	dst,
		off_t	dst_offset,
		off_t	length
	)

Copies data from a bless_buffer_t to another.

Parameters:

	src	the bless_buffer_t to read data from
	src_offset	the offset in the source bless_buffer_t to start reading from
	dst	the bless_buffer_t to copy data to
	dst_offset	the offset in the destination bless_buffer_t to start copying data to
	length	the length of the data to read

Returns:: the operation error code

Definition at line 408 of file buffer_edit.c.

int bless_buffer_find	(	bless_buffer_t *	buf,
		off_t *	match,
		off_t	start_offset,
		void *	data,
		size_t	length,
		bless_progress_func *	progress_func
	)

Searches for data in a bless_buffer_t.

Parameters:

	buf	the bless_buffer_t to search
`[out]`	match	the offset the data was found at or -1 if no match was found
	start_offset	the offset in the bless_buffer_t to start searching from
	data	a pointer to the data to search for
	length	the length of the data to search for
	progress_func	the bless_progress_cb to call to report the progress of the operation or NULL to disable reporting

Returns:: the offset in the bless_buffer_t where a match was found or an operation error code

Definition at line 434 of file buffer_edit.c.

static int read_foreach_func	(	segcol_t *	segcol,
		segment_t *	seg,
		off_t	mapping,
		off_t	read_start,
		off_t	read_length,
		void *	user_data
	)			`[static]`

A segcol_foreach_func that reads data from a segment_t into memory.

Parameters:

	segcol	the segcol_t containing the segment
	seg	the segment to read from
	mapping	the mapping of the segment in segcol
	read_start	the offset in the data of the segment to start reading
	read_length	the length of the data to read
	user_data	a void ** pointer containing the pointer to write to

Returns:: the operation error code
