I don't think you need collections. fcntl's third argument varies
according to the command. It is not always needed. Write a c file containing
wrappers that can be called from swift for the various commands you need. I'm
thinking something like this (untested).
int
fcntl_dupfd(int fildes, int arg)
{
return fcntl(fildes, F_DUPFD, arg);
}
int
fcntl_getlk(int fildes, struct flock *arg)
{
return fcntl(fildes, F_GETLK, arg)
}
etc. Will that work?
