A function pointer to a LIBMEM driver's read extended function.
-
Parameters:
-
|
h
|
A pointer to the handle of the LIBMEM driver. |
|
dest
|
A pointer to the initial memory address to write data to. |
|
src
|
A pointer to the initial memory address in the memory range handled by the driver to read data from. |
|
size
|
The number of bytes to write. |
-
Returns:
- The LIBMEM status result.
The driver's read function is an optional extended function. It has been provided to allow you to write a driver for memory that is not memory mapped.
Typically memory read operations will be direct memory mapped operations however implementing a driver's read function allows you to access non-memory mapped memory through the LIBMEM interface.
