WriteToPhysicalMemory
int
status = WriteToPhysicalMemory (
unsigned int
physicalAddress,
void
*sourceBuffer,
unsigned int
numberOfBytes);
Note: This function is available only on the Windows versions of LabWindows/CVI.
Purpose
Copies the contents of destinationBuffer into a region of physical memory. The function does
not check whether the memory actually exists. If the memory does not exist, the success value is
returned but no data is read.
Note: For you to be able to use this function under Windows 95 or NT, the LabWindows/CVI
low-level support driver must be loaded.
Parameters
Input
physicalAddress
unsigned integer The physical address to be written
to. There are no restrictions on
the address; it can be below or
above 1 MB.
sourceBuffer
void pointer The buffer from which the
physical memory will be copied.
numberOfBytes
unsigned integer The number of bytes to copy to
physical memory.
