Comparison of Windows and Linux synchronization APIs

Initialize critical section

(Win)

InitializeCriticalSection (rtl_critical_section &rtl_critial_section)

(Linux)

Pthread_mutexattr_init (& (Mutex)->attr);

Pthread_mutexattr_settype (& (Mutex)->attr, pthread_mutex_recursive);

Pthread_mutex_init (& (Mutex)->MTX, & (Mutex)->attr);

Delete a critical section

(Win)

DeleteCriticalSection (Rtl_critical_section &)

(Linux)

Pthread_mutex_destroy (pthread_mutex_t &mutex)

Enter the critical section

(Win)

EnterCriticalSection (rtl_critical_section &rtl_critical_section)

(Linux)

Pthread_mutex_lock (pthread_mutex_t &mutex)

Try to enter the critical section

(Win)

TryEnterCriticalSection (rtl_critical_section &rtl_critical_section)

(Linux)

Pthread_mutex_trylock (pthread_mutex_t &mutex)

Leave the critical section

(Win)

LeaveCriticalSection (rtl_critical_section &rtl_critical_section)

(Linux)

Pthread_mutex_unlock (pthread_mutex_t &mutex)

Compares the target operand (the number of memory pointed to by the 1th parameter) with a value (the 3rd parameter) and, if equal, with another value (the 2nd parameter) and the target operand (the number of memory pointed to by the 1th parameter); InterlockedExchange is not a comparison of direct exchanges. The entire operation is locked in memory, other processors do not access the memory at the same time, thus enabling thread mutexes in multiprocessor environments

(Win)

InterlockedCompareExchange (Destination, NewValue, Oper)

(Linux)

__sync_val_compare_and_swap (Destination, Oper, newvalue)

V The value of the atom adds the size of P

(Win)

InterlockedExchangeAdd (V, P)

(Linux)

__sync_fetch_and_add (V, P)

Atoms Add a

(Win)

InterlockedIncrement (T)

(Linux)

__sync_fetch_and_add (T, 1)

Atoms reduce One

(Win)

InterlockedDecrement (T)

(Linux)

__sync_fetch_and_sub (T, 1)

Gets the current thread ID

(Win)

GetCurrentThreadID ()

(Linux)

Syscall (Sys_gettid)

If you specify a value other than 0, the function waits until the Hhandle tag object is triggered, or the time is up. If Dwmilliseconds is 0, the object is not signaled, and the function does not enter a wait state, and it always returns immediately. If Dwmilliseconds is infinite, the function will not return until the object is signaled. The corresponding Linux implementations use condition variables

(Win)

WaitForSingleObject (Event,infinite)

(Linux)

Pthread_mutex_lock (&M_TX);
Pthread_cond_wait (&event, &M_TX);
Pthread_mutex_unlock (&M_TX);

Exit thread (exit parameter 0)

(Win)

ExitThread (0)

(Linux)

Pthread_exit (0)

Set thread priority, Pthread_setschedparam is often used in multithreaded development, and is used primarily to set thread invocation policies and priorities

(Win)

SetThreadPriority (Handle,nprioroty)

(Linux)

Sched_param sp = {npriority};
if (0 = = Pthread_setschedparam (M_pid, SCHED_RR, &SP))
{
return true;
}
return false;

Get priority level

(Win)

GetThreadPriority (Handle m_hthread)

(Linux)

int policy;
Sched_param sp;
Pthread_getschedparam (M_pid, &policy, &SP))
sp.sched_priority;

Initialize Mutex amount

(Linux)

Pthread_mutex_init (pthread_mutex_t &mutex), 0)

Initializing condition variables

Pthread_cond_init (&cond,0)

Delete Mutex amount

Pthread_mutex_destroy (pthread_mutex_t &mutex))

Delete a condition variable

(Linux)

Pthread_cond_destroy (pthread_cond_t &cond)

Signaling to a condition variable

(Linux)

Pthread_cond_signal (pthread_cond_t &cond)

Suspend wait end (infinite wait) true to allow access to warning state during blocking (Windows only)

(Win)

WaitForSingleObject Ex (handle, Infinite,true)

(Linux)

Pthread_join (pthread_t thid, void * * ret_val) Common pthread_join (pid,0)
