byte - In C programming, what does "emit" do? -


i tried expand knowledge of c language , came across program used emit, possibly emit byte.

__declspec(naked) void marker_begin() { __asm {     _emit 0x51;     _emit 0x21;     _emit 0x1a;     _emit 0x14;     _emit 0x2c;     _emit 0x5b; }

}

what used for? in advance.

your c program executing inline assembly code using _asm keyword. _asm microsoft specific keyword used in msdn. __asm keyword invokes inline assembler. must followed assembly instruction, group of instructions enclosed in braces, or, @ least, empty pair of braces.

the _emit pseudo instruction similar db directive of masm. _emit msdn specific pseudo instruction. _emit used define single immediate byte @ current location in current text segment. _emit can define 1 byte @ time , in text segment.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
