thanx for explaining. it was clearer than the man page. so the way it is in now is better as it produces no warning.

IRC.cpp:280: strtok(NULL, " =");

but what are the required side-effects? Again: I feel
terribly sorry to have caused confusion, but i'd like to know.


man strtok ;-)

More seriously, strtok, when called with a non NULL first parameter, take this string and return the first token, by adding a trailing 0 at the end of the token (so in the middle of the input string). When called with NULL, it continues on the same input string, returning the next token, and put a trailing 0 at the end of the token (so probably still in the middle of the input string). So if you remove a strtok, the next strtok will not return the same token.

This sad, strtok is a bad function because of this side effect thing. It is thus also non thread-safe.
