MSIPATCHSEQUENCEINFOW structure (msi.h)

The MSIPATCHSEQUENCEINFO structure is used by the MsiDeterminePatchSequence and MsiDetermineApplicablePatches functions.

Syntax

typedef struct tagMSIPATCHSEQUENCEINFOW {
  LPCWSTR          szPatchData;
  MSIPATCHDATATYPE ePatchDataType;
  DWORD            dwOrder;
  UINT             uStatus;
} MSIPATCHSEQUENCEINFOW, *PMSIPATCHSEQUENCEINFOW;

Members

szPatchData

Pointer to the path of a patch file, an XML blob, or an XML file.

ePatchDataType

Qualifies szPatchData as a patch file, an XML blob, or an XML file.

0
The szPatchData member refers to a path of a patch file.
MSIPATCH_DATATYPE_XMLPATH

dwOrder

Set to an integer that indicates the sequence of the patch in the order of application. The sequence starts with 0. If a patch is not applicable to the specified .msi file, or if the function fails, dwOrder is set to -1.

Remarks

Note

The msi.h header defines MSIPATCHSEQUENCEINFO as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
