Thread: strings

Try memset()
-initialize it with '\0' 's
-size_t can be sizeof(array)

memset will do exactly what you wanted to, but...

I really can see no reason for you to even worry about clearing the buffer. You're still writing 80 bytes, and you're never going to see anything past the '\0' character in the string. I'd bee more concerned with overwriting your buffer. It seems like a wasted function call to me, but I really don't know everything now do I?

Okay, maybe I rushed to post a reply because this place has not been seeing any action. You can use memset to initialize an array, especially a dynamically allocated array. A automatic array is easy enough to initialize with a loop. In this program you probably don't need it memset. Maybe just define a buffer size of 256 which is the max of unsigned char, and than scan until you reach the newline character. If you want more protection than that, than you might have to reallocate your buffer but that means a lot more work and in most situations isn't necessary. It is more difficult to give advice when there is no code to base an answer on.
