pub struct Process { /* fields omitted */ }

Windows process representation

Methods

impl Process

fn open(pid: u32, access_rights: u32) -> Result<Process>

Creates handle to a new process by opening it through pid.

Note:

See information about access rights: https://msdn.microsoft.com/en-us/library/windows/desktop/ms684880%28v=vs.85%29.aspx

Parameters:

• pid - Pid of the process.
• access_rights - Bit mask that specifies desired access rights.

Return:

• Ok - Process struct.
• Err - Error reason.

fn from_raw(handle: HANDLE) -> Self

Creates instance from existing handle

fn inner(&self) -> HANDLE

Retrieves underlying handle.

fn into_inner(self) -> HANDLE

Retrieves underlying handle and consumes self.

Basically you're responsible to close handle now.

fn exe_path(&self) -> Result<String>

Gets full path to process's exectuable.

Note

The process MUST be opened with either PROCESS_QUERY_INFORMATION or PROCESS_QUERY_LIMITED_INFORMATION flag.

Return

• Ok - Success.
• Err - Error reason.

fn window(&self) -> Result<Option<HWND>>

Retrieves handle to process's window

Note

It can return None if process hasn't created window.

fn read_memory(&self, base_addr: usize, storage: &mut [u8]) -> Result<()>

Reads memory from process.

Parameters:

• base_addr - Address from where to start reading.
• storage - Storage to hold memory. Its len determines amount of bytes to read.

fn write_memory(&self, base_addr: usize, data: &[u8]) -> Result<()>

Writes into process memory.

Parameters:

• base_addr - Address from where to start writing.
• data - Slice with write data.

Return:

• Ok - Success.
• Err - Error reason.

fn close(&mut self)

Closes process

Note:

There is no need to explicitly close the process.

It shall be closed automatically when being dropped.

fn terminate(self, exit_code: c_uint) -> Result<()>

Forces termination of process and consumes itself.

For details see raw::process::terminate().

Trait Implementations

fn drop(&mut self)

A method called when the value goes out of scope.
