For starters, this function should be rewritten as
static void *coms(void *arg)
{
int fd;
fd = *(int *)arg;
pthread_detach(pthread_self());
write(fd, "Test", 4);
close(fd);
return (NULL);
}
Because you're passing the _address_ of `confd', not the
value. You must first cast arg to an int pointer, and then
dereference it (and assign its value to `fd').
