ApplyDeltaB function

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

BOOL  WINAPI  ApplyDeltaB(
    DELTA_FLAG_TYPE  ApplyFlags,
    DELTA_INPUT      Source,
    DELTA_INPUT      Delta,
    LPDELTA_OUTPUT   lpTarget
   );

Parameters

ApplyFlags

[in] Either DELTA_FLAG_NONE or DELTA_APPLY_FLAG_ALLOW_PA19.

Source

[in] A DELTA_INPUT structure containing a pointer to the buffer containing the source data.

Delta

[in] A DELTA_INPUT structure containing a pointer to the buffer containing the delta data.

lpTarget
