Makeword ()

Makeword macro platform: SDK creates a word variable connected by a specified variable. Returns a word variable. (Note: typedef unsigned short word;) Word makeword (byte blow, // specify the low byte order of the new variable; byte bhigh // specify the high byte order of the new variable ;); for example: Word wversionrequested; wversionrequested = makeword (2, 2); # define makeword (A, B) (Word) (byte) (a) | (word) (byte) (B) <8) makeword combines two byte types into one word type, one in high 8-bit (B ), A low 8-bit (a) makelparam, makelong, and makewparam are the same, and the two word types are combined into a DWORD type. A high 16-bit, a low 16-bit such as a = 2; B = 1 2 binary is 00000010 1 binary is 00000001 B represents a high 8-bit, A indicates that the lower 8 bits are merged as 100000010 For example: # include <iostream. h> # include <windows. h> using namespace STD; int main () {word wversionrequested; wversionrequested = makeword (514); cout <wversionrequested <Endl; return 0;} outputs, the preceding two and the following two form a new word. That is, 0000 0010 0000 0010, and the result is: 512 + 2 = 514.
