Module user::syscall

All syscalls of core-os

Syscalls of core-os are defined and implemented with Rust primitives (e.g. str, [u8]). This module will transmute these Rust primitives into pointers and other machine-specific representations before calling functions in syscall_internal and trapping into kernel.

Usage of syscalls is listed in their corresponding sub-page.
