c# - How can I use a method's (whose argument has been passed by ref) return value in Main() -


i have following c# code:

public class test  {      public string docs(ref innovator inn) ///innovator object defined in   framework of application     {           //// code          string file_name = "filename";         return file_name;     }        public static void main ()/// here i' m trying use above method' s return value inside main()     {          test t = new test();          string file_name1 = t.docs(ref inn);      } }

this sample code throwing errors.

  1. 'inn' does' t exists in current context,
  2. method has invalid arguments.

why this?

1: 'inn' does' t exists in current context,

you haven't defined inn anywhere in code. should like:

test t = new test(); innovater inn = new innovator(); //declare , (instantiate) string file_name1 = t.docs(ref inn);

or can inn framework like:

innovater inn = getinnovaterfromtheframework();

where method getinnovaterfromtheframework return object framework.

the way passing argument parameter ref keyword right, thing inn doesn't exist in current context.

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).
