Dmitry:
Are you suggesting that in the definition of, for example, dbgsysConnect(), we
convert the namelen argument to be a socklen_t?
int
dbgsysConnect(int fd, struct sockaddr *name, uint32_t namelen) {
int rv = connect(fd, name, (socklen_t)nameLength);<--- NEW
if (rv < 0 && (errno == EINPROGRESS || errno == EINTR)) {
return DBG_EINPROGRESS;
} else {
return rv;
}
}
Thanks!
John

connect, recvfrom etc almost always uses socklen_t, but socklen_t could
expands either to int or to unsigned it on different OS
so as soon as the code pass a parameter directly to one of such
functions like e. g.
52 dbgsysConnect(int fd, struct sockaddr *name, uint32_t namelen) {
53 int rv = connect(fd, name, namelen);
on my opinion, we should use socklen_t
