因爲它不會成功返回，execve之後的界限是什麼？

Question

26: execve(prog[0],prog,env); 
27: return 0; 


execve() does not return on success, and the text, data, bss, and 
     stack of the calling process are overwritten by that of the program 
     loaded. 

什麼是return 0;？

Answer 1

我建議它停止這個編譯器警告。

$ cat | gcc -W -Wall -x c - 
int main(){} 
^D 
<stdin>: In function 'main': 
<stdin>:1:1: warning: control reaches end of non-void function 

這也將使快樂的靜態分析儀和IDE警告關於同樣的事情。
