dfu_target_init()

int dfu_target_init	(	int	img_type,
		int	img_num,
		size_t	file_size,
		dfu_target_callback_t	cb
	)

#include <include/dfu/dfu_target.h>

Initialize the resources needed for the specific image type DFU target.

If a target update is in progress, and the same target is given as input, then calling the 'init()' function of that target is skipped.

To allow continuation of an aborted DFU procedure, call the 'dfu_target_offset_get' function after invoking this function.

Parameters

[in]	img_type	Image type identifier.
[in]	img_num	Image pair index. Value different than 0 are supported only for DFU_TARGET_IMAGE_TYPE_MCUBOOT image type currently.
[in]	file_size	Size of the current file being downloaded.
[in]	cb	Callback function in case the DFU operation requires additional procedures to be called.

Returns

0 for a supported image type or a negative error code indicating reason of failure.
