System call replacement matrix for the library
| Linux Call | QNX Equivalent | Critical Differences |
|---|---|---|
| fork() | spawn(), spawnp() | QNX version doesn't copy entire address space |
| epoll_wait() | ionotify() and InterruptWait() | Requires event server setup |
| inotify | devctl() and resource manager | More complex but more flexible |
| timerfd() | TimerCreate() and SIGEV_PULSE | Insted of file descriptor, QNX uses message/pulse |
