The prototype for __emit__ has been removed from DOS.H. __emit__ is
still supported, but is now automatically recognized by the compiler and
provides some new features, now that it's un-prototyped:
__emit__ usually works with constant numbers of size char, short, long,
and __int64, however, there are three special additions here:
int x;
__emit__(&x);
This will emit the address of the variable x in the correct little-endian
form to be used in assembly operations.
__emit__(1.234F);
__emit__(1.234);
__emit__(1.234L);
These emit the 4, 8, or 10 byte pattern that represents the constant
float, double, or long double values of 1.23.
__emit__("Hello There");
This will create a constant string (just like the compiler does with
any constant string in C or C++) and emits the 4-byte address of this
string.
There is a special byte-saving optimization made if a signed
int constant number is specified: the fewest number of bytes required
to represent that number will be emitted. If the same value is cast
or suffixed to be unsigned int instead, the full size is emitted. Keep
in mind that all integral literals are, by definition, signed integers
(unless an alternate suffix is applied):
__emit__(0); // yields an 8-bit 00h not a 32-bit 00000000h
use __emit__(0u) to get 32-bits.
__emit__(0x64); // yields an 8-bit 64h
__emit__(100u); // yields a 32-bit 00000064h
__emit__(0x64u); // yields a 32-bit 00000064h
__emit__((char) 50); // yields an 8-bit 32h
__emit__((short) 500); // yields a 16-bit 01F4h
__emit__(2ui64); // yields a 64-bit 0000000000000002h
__emit__(20i64); // yields a 64-bit 0000000000000014h
Multiple parameters can be passed to __emit__ and they will be generated
from left to right (similar to the pascal calling convention). The left
most parameter will be emitted to a lower address in memory than the
right most parameter.
__emit__(0,1,2,3,4); // yields 5 bytes: 0001020304
__emit__(L'\x8C\x1F', 0, 300i64); // yields 11 bytes:8C1F001201000000000000
