What should I do to get the whole return value of c-program from command line?

Question

I have a simple C-program \"./my_program\"

#include 

int main (int argc , char **argv) {


   unsigned int return_result = 0x474         


        

Answer 1

Exit codes on Unix are restricted to a single byte. If you want to output more, you could write it to stdout or to a file instead.

Then why does the C standard decree that main returns int and not char? I have no idea...
