Munmap v0.1.0

Removes a virtual-memory mapping.

Package: Linux

Signature

func Munmap(addr: *opaque, length: uint) -> int64;

Name	Type	Description
`addr`	`*opaque`	Page-aligned start of the range to unmap.
`length`	`uint`	Number of bytes in the range.

int64 — 0 on success, or a negative errno result on failure.

After a successful call, accessing the unmapped range is invalid. The address must be page-aligned; Linux rounds length up to a page boundary.

import Linux::{ IsError, Munmap };

func Main() -> int {
    if IsError(Munmap(memory, 4096u)) {
        return 1;
    }
    return 0;
}
