Of course, but everyone wants to overdo the complexity of the time worn solution. OMG you need to null terminate the string after all the _other_ gymnastics..gee C sure does suck! Why don't we use rust|go|c++ ad-nauseam. bzero(buf,sz); /memset nazis here/ strncpy(buf,src,sz - 1);

It doesn't make sense to have to null-terminate the string by hand (maybe) after doing a "safe" STRING copy. Which means it's easy to forget to do and that's a dangerous wart in the design.

Really, stop using C. To quote Hayao Miyazaki, C was a mistake.

What I meant is more like:

    #define BUFSIZE 100
    char buf[BUFSIZE+1]
    buf[BUFSIZE]=0 // for global var, it is already zeroed, right?

Then one can call strncpy(buf, BUFSIZE, ...) without worrying about null-termination.
