Addon for I/O buffering

Functions
M_io_error_t	M_io_add_buffer (M_io_t *io, size_t *layer_id, size_t max_read_buffer, size_t max_write_buffer)

Detailed Description

Intermediate layer for buffering reads/writes from the OS.

Allows data to be buffered, this can reduce the number of syscalls required to the OS and increase performance at the cost of memory.

Function Documentation

M_io_add_buffer()

M_io_error_t M_io_add_buffer	(	M_io_t *	io,
		size_t *	layer_id,
		size_t	max_read_buffer,
		size_t	max_write_buffer
	)

Add a buffer layer. Cannot be combined with base IO objects which utilize M_io_meta_t.

Parameters

[in]	io	io object.
[out]	layer_id	Layer id this is added at.
[in]	max_read_buffer	Maximum read buffer size in bytes. If not a power of 2 will be rounded up to the next power of 2. Use 0 to disable read buffering.
[in]	max_write_buffer	Maximum write buffer size in bytes. If not a power of 2 will be rounded up to the next power of 2. Use 0 to disable write buffering.

Returns
