syscall #

System Calls

The system call is the fundamental interface between an application and the operating system kernel.

syscall module provides wrappers for system calls. Use C.syscall() if you want to invoke system calls that has no wrappers.

Status and Purpose

This project is currently a Work in Progress (WIP). Breaking changes may occur prior to reaching version 1.0.0.

The objective of this module is to provide C wrappers that are currently missing from V's standard os library. However, this does not preclude the inclusion of wrappers for system calls that are already present in the standard library. Consequently, the syscall module does not aim to provide comprehensive coverage of all system calls; rather, the number of wrappers will be expanded on an as-needed basis.

Microsoft Windows support is not planned.

fn C.syscall #

unsafe

fn C.syscall(i32, ...voidptr) i32

C.syscall calls syscall indirectly.

Example

import syscall

pid := C.syscall(syscall.sys_getpid)
println(pid)

fn chroot #

fn chroot(path string) !

chroot changes the root directory of the calling process. See chroot(2) for details.

Note: Only privileged process may call chroot(). On Linux CAP_SYS_CHROOT capability is required.

fn close #

fn close(fd int) !

close closes the file descriptor. See also close(2).

fn fork #

fn fork() !int

fork creates a new process and returns it's PID. See also fork(2).

fn kill #

fn kill(pid i32, sig i32) !

kill sends signal sig to process identified by pid. See also kill(2).

fn lseek #

fn lseek(fd int, offset isize, whence i32) !isize

lseek repositions read/write file offset. See also lseek(2).

fn mount #

fn mount(source string, target string, filesystemtype string, mountflags u64, data voidptr) !

mount mounts the filesystem.

Linux: See mount(2).

FreeBSD: The source argument is ignored. See mount(2).

fn open #

fn open(path string, flags i32, mode i32) !int

open opens and possibly creates a file. See open(2) for details.

fn pipe #

fn pipe() !(int, int)

pipe creates pipe. See also pipe(2).

fn pipe2 #

fn pipe2(flags i32) !(int, int)

pipe2 creates pipe. See also pipe(2).

fn pread #

fn pread(fd int, mut buf []u8, count usize, offset isize) !int

pread reads up to count bytes from file descriptor fd at offset offset (from the start of the file) into the buffer buf. The file offset is not changed. See also pread(2).

fn pwrite #

fn pwrite(fd int, buf []u8, count usize, offset isize) !int

pwrite writes up to count bytes from the buffer buf to the file descriptor fd at offset offset. The file offset is not changed. See also pwrite(2).

fn read #

fn read(fd int, mut buf []u8, count ?usize) !int

read reads data from the file descriptor fd into the buf buffer. If count is not set the buf.len bytes will read. See also read(2).

fn unlink #

fn unlink(path string) !

unlink deletes a name and possibly the file it refers to. See also unlink(2).

fn unmount #

fn unmount(target string, flags i32) !

unmount unmounts the filesystem mounted to target.

Linux: See umount(2). If flags is non-zero umount2 is called instead of umount.

FreeBSD: See unmount(2).

fn write #

fn write(fd int, buf []u8, count ?usize) !int

write writes data from buf into the file descriptor fd. If count is not set the buf.len bytes will written. See also write(2).
