PackageFullNameFromId function

Gets the package full name for the specified package identifier (ID).

Syntax


LONG WINAPI PackageFullNameFromId(
  _In_       const PACKAGE_ID *packageId,
  _Inout_    UINT32 *packageFullNameLength,
  _Out_opt_  PWSTR packageFullName
);

Parameters

packageId [in]

Type: const PACKAGE_ID*

The package ID.

packageFullNameLength [in, out]

Type: UINT32*

On input, the size of the packageFullName buffer, in characters. On output, the size of the package full name returned, in characters, including the null terminator.

packageFullName [out, optional]

Type: PWSTR

The package full name.

Return value

Type: LONG

If the function succeeds it returns ERROR_SUCCESS. Otherwise, the function returns an error code. The possible error codes include the following.

Return codeDescription
ERROR_INSUFFICIENT_BUFFER

The buffer is not large enough to hold the data. The required size is specified by packageFullNameLength.

 

Remarks

For info about string size limits, see Identity constants.
