(

)

const [inherited]

Returns the number of references.

bool mds::base::CObject::isOnHeap

(

)

const [inherited]

Returns true if the object is allocated on the heap.

void mds::sys::CSemaphore::lock

(

)

Locks the semaphore.

• Decreases the semaphore value by one.

mds::sys::CSemaphore::MDS_SHAREDPTR

(

CSemaphore

)

Smart pointer type.

static void* mds::base::CObject::operator new

(

std::size_t

Size

)

[static, inherited]

void mds::sys::CSemaphore::unlock

(

int

iValue = 1

)

Releases the semaphore.

• Increases the value.
