MI_WriteDevice

Syntax

#include <nitro/mi.h>

  

  int MI_WriteDevice(MIDevice *device, const void *buffer, u32 offset, u32 length);

Arguments

device	Pointer to the `MIDevice` structure to access. The device must have been initialized using `MI_InitDevice()`.
buffer	The transfer source memory where the data for writing is stored.
offset	The starting address in the device where data should be written.
length	The data write size.

Return Values

If the function succeeds, it will return the actual amount of data that has been read. If it fails, it will return a negative value.

Description

Writes the data to a device using the MIDevice structure.
Internally, this just calls the callback function for writes specified in MI_InitDevice().

This is a utility feature designed to separate the device control component from the module design. For more information, see the reference for the MIDevice structure.
