Detailed Description

Defines the inline interrupt locking routines.

These routines are just the inline versions of the VxWorks intLock and intUnlock routines. These services can really only be provided on PPC. The implementation is dependent on the GNU compiler.

Function Documentation

int INT__context (  void   )

Return non-zero if a interrupt level. Return values: !=  0, if at interrupt level ==  0, if not at interrupt level (i.e. at task level)

int INT__lock (  void   )

Locks interrupts. Return values: A  key to be passed to the INT__unlock routine

void INT__unlock (  int  key  )

Unlocks the interrrupts. Parameters: key  The key to unlock the interrupt. This is the return value of INT_lock().
