4–52 RAC6182-Specific Extensions to the CE API
Publication 6182-UM002B-EN-P
Parameter Description
dwOffset Starting offset in RAM at which data will be written.
Offset 0 is the first byte of RAM.
dwLength Number of bytes to be written.
pbtBuffer Pointer to a buffer containing data to be written to
the RAM.
Return Value
Returns the total number of bytes actually written
Portability
This function is specific to the RAC6182 hardware.

RetMemRead
RetMemRead
This function reads retentive memory. It is prototyped in
RetentiveMemAPI.h.
Syntax
#include
#include
DWORD RetMemRead (DWORD dwOffset, DWORD dwLength, BYTE *pbtBuffer)
Remarks
This function copies dwLength bytes of data from an area of retentive
memory into a user data buffer. The number of bytes actually read is
returned. If fewer than dwLength bytes are available, the value returned
will be less than dwLength. If another process has the memory locked,
no bytes will be read and the return value will be 0.
The total amount of available memory (in bytes) is given by the macro
RET_MEM_MEMORY_SIZE, defined in RetentiveMemAPI.h.
Parameter Description
dwOffset Starting offset in RAM of data to be read. Offset 0 is
the first byte of RAM.
dwLength Number of bytes to be read.
pbtBuffer Pointer to the beginning of a buffer to be filled with
data from RAM.
