Detailed Description

Core class that represents a counting semaphore.

Member Function Documentation

◆ GetCount()

unsigned int Nz::Semaphore::GetCount ( ) const

Gets the number of count that can handle the semaphore.

Returns: Number of count associated with the semaphore

◆ Post()

void Nz::Semaphore::Post ( )

Increments the count of the semaphore and wait if count equals zero.

Increments the value of semaphore variable by 1. After the increment, if the pre-increment value was negative (meaning there are processes waiting for a resource), it transfers a blocked process from the semaphore's waiting queue to the ready queue

◆ Wait() [1/2]

void Nz::Semaphore::Wait ( )

Decrements the count of the semaphore and wait if count equals zero.

If the value of semaphore variable is not negative, decrements it by 1. If the semaphore variable is now negative, the process executing Wait is blocked (i.e., added to the semaphore's queue) until the value is greater or equal to 1. Otherwise, the process continues execution, having used a unit of the resource

◆ Wait() [2/2]

bool Nz::Semaphore::Wait ( UInt32 timeout )
