Hello list,
Can someone enlighten me on the use of the second parameter of debug(), and first
parameter of
info(), warning() functions?
I originally thought that it indicates the error level, but after some experiments and
delving into the code
I see:
void debug(const char *place, int e, const char *fmt, ...)
{
if (place_should_be_logged(place) && place_is_not_logged(place) == 0) {
/*
* Note: giving `place' to FUNCTION_GUTS makes log lines
* too long and hard to follow. We'll rely on an external
* list of what places are used instead of reading them
* from the log file.
*/
if ((e = thread_to[gwthread_self()])) {
FUNCTION_GUTS_EXCL(GW_DEBUG, "");
} else {
FUNCTION_GUTS(GW_DEBUG, "");
}
}
}
The second condition looks very confusing to me:
if ((e = thread_to[gwthread_self()]))
debug() is normally called as debug("gw", 0, "blablabla"), and this will translate as
if ((0 = thread_to[gwthread_self()]))
which does not make sense to me..
Or is this a typo? I mean '=' is supposed to be '=='? :)
