Thread: Strncpy problem.

Hello, I am using strncpy to copy the first line of a multi-line buffer. I have successfully found the amount of characters to the end of the first line, and I have performed a strncpy to copy the first line of the buffer to a char *.

However, some of the characters are being copied incorrectly.

For example, I am trying to copy:

Code:

GET http://en-gb.start2.mozilla.com/firefox?client=firefox-a&rls=org.mozilla:en-GB:official HTTP/1.1 
Host: en-gb.start2.mozilla.com

But the first line is copied as:

Code:

GET http://en-gb.start2.mozilla.com/firefox?client=firefox-a&rls=org.mozillbÛ¿¸aÛ¿:official HTTP/1.1

Or as:

Code:

GET http://en-gb.start2.mozilla.com/firefox?client=firefox-a&rls=org.mozillLþ¿ÿ-GB:official HTTP/1.1

(bold = problem)


How can I fix this problem?

Thank you in advance,
Matthew

CHEERS!, I ensured that the final character is a ' \0 ' and it works..

Thanks.
