Field Detail

mutexes

protected com.oracle.svm.core.windows.WindowsVMMutex[] mutexes

All mutexes, so that we can initialize them at run time when the VM starts.

conditions

protected com.oracle.svm.core.windows.WindowsVMCondition[] conditions

All conditions, so that we can initialize them at run time when the VM starts.

syncStructs

protected byte[] syncStructs

Raw memory for the Condition Variable structures. Since we know that native image objects are never moved, we can safely hand out pointers into the middle of this array to C code. The offset into this array is stored in WindowsVMMutex.structOffset and WindowsVMCondition.structOffset.
