PackageIdFromFullName function (appmodel.h)

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

Syntax

LONG PackageIdFromFullName(
  [in]            PCWSTR       packageFullName,
  [in]            const UINT32 flags,
  [in, out]       UINT32       *bufferLength,
  [out, optional] BYTE         *buffer
);

Parameters

[in] packageFullName

Type: PCWSTR

The full name of a package.

[in] flags

Type: const UINT32

The package constants that specify how package information is retrieved. The PACKAGE_INFORMATION_* flags are supported.

[in, out] bufferLength

Type: UINT32*

On input, the size of buffer, in bytes. On output, the size of the data returned, in bytes.

[out, optional] buffer

Type: BYTE*

The package ID, represented as a PACKAGE_ID structure.

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.

Remarks

If flags specifies PACKAGE_INFORMATION_BASIC, the following fields are retrieved:

• name
• processorArchitecture
• publisherId
• resourceId
• version

• name
• processorArchitecture
• publisher
• publisherId
• resourceId
• version
