[−][src]Function region::query

pub fn query(address: *const u8) -> Result<Region>

Queries the OS with an address, returning the region it resides within.

The implementation uses VirtualQuery on Windows, mach_vm_region on macOS, kinfo_getvmmap on FreeBSD, and parses proc/[pid]/maps on Linux.

The enclosing region can be of multiple page sizes.
The address is rounded down to the closest page boundary.
The address may not be null.

Examples

use region::{Protection};

let data = [0; 100];
let region = region::query(data.as_ptr()).unwrap();

assert_eq!(region.protection, Protection::ReadWrite);
