Functions

sys_fork

sys_mmap

sys_munmap

Unmap program memory and memory-mapped devices/files

sys_pipe

Create a pipe

sys_wait

Wait for any of the caller’s child-process’s scheduling-statuses to change (not including going from idle to runnable, more signal related statuses; see manpage wait(2))
