Hi, I was having a tour in the kernel sources and I found some codes that I can't understand why. Like this in ppp:
int ppp_init (struct device *dev) { static int first_time = 1; <== define to 1 int answer = 0;
if (first_time) { <== check if is 1, why ? any special special reason? first_time = 0; answer = ppp_first_time(); if (answer == 0) (void) register_symtab (&ppp_syms); } if (answer == 0) answer = -ENODEV; return answer; }
I found many more codes like this in the source, I cant remeber where anymore.
