In C programming, what does "emit" do?
byte, c, emit
Solution
Your C program is executing inline assembly code by using the `_asm` keyword. _asm is a Microsoft specific keyword used in `MSDN`. The `__asm` keyword invokes the inline assembler. It must be followed by an assembly instruction, a group of instructions enclosed in braces, or, at least, an empty pair of braces.
The `_emit` pseudo instruction is similar to the `DB` directive of `MASM`. `_emit` is an `MSDN` specific pseudo instruction. `_emit` is used to define a single immediate byte at the current location in the current text segment. `_emit` can define only one byte at a time and only in the text segment.
Problem
I recently tried to expand my knowledge of the C language and I came across a program that used emit, to possibly emit a byte. ``` __declspec(naked) void marker_begin() { __asm { _emit 0x51; _emit 0x21; _emit 0x1A; _emit 0x14; _emit 0x2C; _emit 0x5B; } ``` } What could this be used for? Thanks in advance.
