Table 1. Synchronization mapping

Windows	Linux -- threads	Linux -- process
Mutex	Mutex - pthread library	System V semaphores
Critical section	Mutex - pthread library	Not applicable as critical sections are used only between the threads of the same process
Semaphore	Conditional Variable with mutex - pthreads POSIX semaphores	System V Semaphores
Event	Conditional Variable with mutex - pthreads	System V Semaphores

Table 2. Semaphore mapping

Windows	Linux Threads	Linux Process	Classification
CreateSemaphore	sem_init	semget semctl	Context specific
OpenSemaphore	Not applicable	semget	Context specific
WaitForSingleObject	sem_wait sem_trywait	semop	Context specific
ReleaseSemaphore	sem_post	semop	Context specific
CloseHandle	sem_destroy	semctl	Context specific
