Function Documentation

◆ TestSynchCritical()

int TestSynchCritical	(	int	argc,
		char *	argv[]
	)

We have to be able to detect dead locks in this test. At the time of writing winpr's WaitForSingleObject has not implemented timeout for thread wait

Workaround checking the value of bThreadTerminated which is passed in the thread arg

Here is the call graph for this function:

◆ TestSynchCritical_Main()

static DWORD WINAPI TestSynchCritical_Main ( LPVOID arg )

static

Test SpinCount in SetCriticalSectionSpinCount, InitializeCriticalSectionEx and InitializeCriticalSectionAndSpinCount SpinCount must be forced to be zero on on uniprocessor systems and on systems where WINPR_CRITICAL_SECTION_DISABLE_SPINCOUNT is defined

Test single-threaded recursive TryEnterCriticalSection/EnterCriticalSection/LeaveCriticalSection

Test using multiple threads modifying the same value

TryEnterCriticalSection in thread must fail if we hold the lock in the main thread
