Function Documentation

opdis_buf_t opdis_buf_alloc	(	opdis_off_t	size,
		opdis_vma_t	addr
	)

Allocate an opdis buffer.

Allocates an opdis_buffer_t of specified size. The buffer contents are initialized to zero.

Parameters:

	size	Size of buffer in bytes.
	addr	Load address (vma) of buffer or 0.

Returns:

The allocated opdis buffer.

See also:

opdis_buf_read opdis_buf_free

int opdis_buf_fill	(	opdis_buf_t	buf,
		opdis_off_t	offset,
		void *	src,
		opdis_off_t	len
	)

Fill an opdis buffer from a memory location.

Parameters:

	buf	Opdis buffer to fill.
	offset	Offset in buf to copy to.
	src	Memory location to copy from.
	len	Number of bytes to copy from src to buf.

Returns:

Number of bytes copied from src to buf.

void opdis_buf_free

(

opdis_buf_t

buf

)

Free an opdis buffer.

Parameters:

buf

Opdis buffer to free.

See also:

opdis_buf_alloc

opdis_buf_t opdis_buf_read	(	FILE *	f,
		opdis_off_t	size,
		opdis_vma_t	addr
	)

Allocate an opdis buffer containing contents of file.

Allocates an opdis buffer and fills it with the contents of the file. This reads size bytes from the current position in f, or from the current position to the end of the file if size is 0.

Parameters:

	f	The file to read from.
	size	The number of bytes to read from the file, or 0.
	addr	Load address (vma) of buffer or 0.

Returns:

The allocated opdis buffer.

See also:

opdis_buf_alloc opdis_buf_free

Note:

The current position of the file will be increased by size bytes upon return.

void opdis_buf_set_vma	(	opdis_buf_t	buf,
		opdis_vma_t	addr
	)

Set the VMA for a buffer.

Parameters:

	buf	The opdis buffer.
	addr	Load address (vma) of buffer or 0.
