[−][src]Struct heliograph::Sem

pub struct Sem(_);

A semaphore on which one can do an operation

Implementations

impl Sem[src]

pub fn op(&self, v: c_short) -> SemOp[src]

Create a semaphore operation doing op

Usually, it is better to use one of the other functions of this type.

See man 2 semop for more details about the semantics here

pub fn add(&self, v: c_short) -> SemOp[src]

Create a semaphore operation adding v to the semaphore

Panics

Panics if v is not strictly positive

pub fn remove(&self, v: c_short) -> SemOp[src]

Create a semaphore operation removing v from the semaphore

Panics

Panics if v is not strictly positive

pub fn wait_zero(&self) -> SemOp[src]

Create a semaphore operation waiting for this semaphore to be zero
