ApplyDeltaB function

  • Article

Uses the delta and source (provided as buffers) to create a new copy of the target data. The output data is returned in an MSDelta-allocated buffer.

Note

You must call DeltaFree to free the output buffer after this function has completed.

Note

If the specified delta was created using PatchAPI, and the DELTA_APPLY_FLAG_ALLOW_PA19 flag is set, MSDelta will call PatchAPI to apply the delta.

Syntax

    DELTA_INPUT      Delta,
