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
