compiler told me the line was not needed. sorry for
believing my compiler :((
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.
