Hi all,
Please review the code below. I need to find the length of the string to which, character pointer stringvar is pointing to:
const char *stringvar = getenv("QUERY_STRING"); /* CGI input */
if i write,
int length = strlen(stringvar);
will it give me the length of complete string?
Yes, strlen gives the length of strings. When in doubt, read the fine man page.
Quzah.
Hope is the first step on the road to disappointment.
Well, you should also read the man page for getenv() and make sure you don't do anything stupid if it can't find the "QUERY_STRING" variable.
