 SwapVectors (procedure)     (Dos unit)


Swaps the SaveIntXX pointers in the System unit with the current vectors.

Declaration

 procedure SwapVectors;

Target

Real, Protected

Remarks

Swaps the contents of the SaveIntXX pointers in the System unit with the current contents of the interrupt vectors. SwapVectors is typically called just before and just after a call to Exec. This ensures that the Exec'd process does not use any interrupt handlers installed by the current process and vice versa.
