Struct Process

pub struct Process { /* private fields */ }

Available on crate feature process only.

A Windows process.

Implementations

impl Process

pub fn current() -> Self

Constructs a special handle that always points to the current process.

When transferred to a different process, it will point to that process when used from it.

pub fn from_id<I>(id: I) -> Result<Self>

where I: Into<ProcessId>,

Tries to acquire a process handle from an ID.

This may fail due to insufficient access rights.

pub fn begin_background_mode() -> Result<()>

Sets the current process to background processing mode.

This will also lower the I/O priority of the process, which will lower the impact of heavy disk I/O on other processes.

pub fn end_background_mode() -> Result<()>

Ends background processing mode for the current process.

pub fn set_priority(&mut self, priority: ProcessPriority) -> Result<()>

Sets the priority of the process.

Examples

use winapi_easy::process::{Process, ProcessPriority};

Process::current().set_priority(ProcessPriority::Normal)?;

pub fn get_io_priority(&self) -> Result<Option<IoPriority>>

Returns the I/O priority of the process.

Will return None if it is an unknown value.

pub fn set_io_priority(&mut self, io_priority: IoPriority) -> Result<()>

pub fn get_id(&self) -> ProcessId

Trait Implementations

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: ProcessId) -> Result<Self, Self::Error>

Performs the conversion.
