ReadRaw16 performs a raw read operation on a volatile SHORT value without any memory ordering or atomicity semantics.
Syntax
SHORT ReadRaw16(
SHORT const volatile *Source
);
Parameters
Source
[in] A pointer to the volatile SHORT variable to read from.
Return value
Returns the SHORT value read from the specified memory ___location.
Remarks
The ReadRaw16 function performs a raw memory read operation on a 16-bit value without compiler optimization barriers or synchronization guarantees. It's useful on strongly-ordered architectures where precise control over memory access is required.
