Constructor & Destructor Documentation

HSEP::Mutex::Mutex

(

bool

pShared = false

)

Creates a concurrent synchronization Mutex.

Parameters

pShared

when true, defines a Mutex that can be used inside a Shared Memory area.

Member Function Documentation

void HSEP::Mutex::acquire

(

)

Acquires the mutex to enter a critical region.

Any other thread and/or process (in the case of Shared mutexes), will be frozen by the operating system until the Mutex is released.

If more than one thread and/or process are frozen, they will be enqueued by the operating system and only one of them will be defrozen when a release method be performed on the Mutex instance.

Definition at line 43 of file POSIX_Mutex.cpp.

void HSEP::Mutex::release

(

)

Releases the mutex to permit others to enter a critical region.

The release call only will defrost one thread. When needing to let more than one Thread to pass, consider the usage of a Dam synchronization primitive.
