Must be in synchronization with Semaphore_Control::variant.

Function Documentation

◆ _Semaphore_Allocate()

RTEMS_INLINE_ROUTINE Semaphore_Control* _Semaphore_Allocate ( void  )

Allocates a semaphore control block from the inactive chain of free semaphore control blocks.

This function allocates a semaphore control block from the inactive chain of free semaphore control blocks.

◆ _Semaphore_Free()

RTEMS_INLINE_ROUTINE void _Semaphore_Free ( Semaphore_Control the_semaphore)

Frees a semaphore control block to the inactive chain of free semaphore control blocks.

This routine frees a semaphore control block to the inactive chain of free semaphore control blocks.
