where to learn precomp coding

[vonLandenhausen]

take a look at this:
#pragma intrinsic(memcmp, memcpy, memset, strcat, strcmp, strcpy, strlen)

#define MAKEIP(b4,b3,b2,b1) ((LPARAM)(((DWORD)(b1)<<24)+((DWORD)(b2)<<16)+((DWORD)(b3)<<+((DWORD)(b4))))
#define RENDIAN_WORD(W) ((HIBYTE(WORD(W)) >> 0) | (LOBYTE(WORD(W)) << )
#define DATA_SIZE 4096

what does it do? where to learn to code something like this? (i never saw a book which treated this stuff.

#define MAKEIP(b4,b3,b2,b1) ((LPARAM)(((DWORD)(b1)<<24)+((DWORD)(b2)<<16)+((DWORD)(b3)<<8)+((DWORD)(b4))))
#define RENDIAN_WORD(W) ((HIBYTE(WORD(W)) >> 0) | (LOBYTE(WORD(W)) << 8))

Modify your post, don't repost... just look at MSDN

The "intrinsic" pragma declaration allows functions to be called inline with argument lists generated at compile-time.

Amazingly enough, I searched MSDN with "#pragma intrinsic" and I found it.  Amazing.

Wasn't there a thread almost exactly like this?
