CriticalSection (Variable type)

In french: SectionCritique

CriticalSection variables are used to define critical sections to limit the simultaneous execution of a code (procedure, line of code, etc.) to one thread at a given moment in an application.

Note: For more details on declaring this type of variable, see Declaring a variable.

Example

// Déclaration
//----------------
S is CriticalSection

// Utilisation pour un bloc de code
//---------------------------
USING S IN
	// code protégé par la section critique
	// un seul thread pourra exécuter ce code à un moment donné
END

Remarks

The CriticalSection type is used to simplify the declaration of critical sections.
CriticalSection variables respect the rules for variable scope.
A block of code can be protected with a critical section via the syntax USE ... IN.
