IFX_EXTERN boolean IfxCpu_acquireMutex ( IfxCpu_mutexLock * lock)

API to acquire the mutex (binary semaphore).

This API can be used to acquire/get the mutex.

Parameters

lock	lock pointer

Returns: TRUE : lock acquired successfully. FALSE: Failed to acquire the lock

IfxCpu_mutexLock resourceLock;
boolean flag = IfxCpu_acquireMutex(&resourceLock);
if (flag){
  // critical section
  IfxCpu_releaseMutex(&resourceLock);
}

IFX_EXTERN void IfxCpu_releaseMutex ( IfxCpu_mutexLock * lock)

API to unlock the mutex .

This API can be used to unlock the previously acquired mutex

Parameters

lock	lock pointer

Returns: None

IfxCpu_mutexLock resourceLock;
boolean flag = IfxCpu_acquireMutex(&resourceLock);
if (flag){
  // critical section
  IfxCpu_releaseMutex(&resourceLock);
}

IFX_EXTERN boolean IfxCpu_setSpinLock	(	IfxCpu_spinLock *	lock,
		uint32	timeoutCount
	)

API to lock the resource in spin mode with the given timeout.

This API can be used to spin lock for the lock for the given timeout period.

Parameters

lock	lock pointer
timeoutCount	loop counter value used for timeout to acquire lock

Returns: TRUE : lock acquired successfully. FALSE: Failed to acquire the lock

IfxCpu_spinLock resourceLock;
boolean flag = IfxCpu_setSpinLock(&resourceLock, 0xFFFF);
if (flag){
  // critical section
  IfxCpu_resetSpinLock(&resourceLock);
}
