RtlQueryPackageIdentityEx returns the associated full package name. It can optionally also return the package relative application name, and whether an application is considered packaged.

Syntax

NTSYSAPI NTSTATUS RtlQueryPackageIdentityEx(
  PVOID    TokenObject,
  PWSTR    PackageFullName,
  PSIZE_T  PackageSize,
  PWSTR    AppId,
  PSIZE_T  AppIdSize,
  LPGUID   DynamicId,
  PULONG64 Flags
);

Parameters

TokenObject

Handle to a token object (user mode) that was opened with TOKEN_QUERY access, or to a raw token object (kernel mode).

PackageFullName

Pointer to a wide character buffer that will receive the unique package key. The buffer will be null terminated upon success.

PackageSize

Pointer to the value that defines the size of the buffer that PackageFullName points to. On output, it will contain the written size including the terminating null.

AppId

Pointer to a wide character buffer that may receive the package relative application identifier. AppId is optional and can be NULL.

AppIdSize

Pointer to the value that defines the size of the buffer that AppId points to. On output, it will contain the written size including the terminating null. If AppId is not NULL, AppIdSize must point to a valid value; otherwise AppIdSize should set to NULL.

DynamicId

Pointer to a value that receives a dynamic ID for the application. DynamicId is optional and can be NULL.

Flags

Pointer to a value that receives a bitmask of values for the package attribute.

RtlQueryPackageIdentityEx returns STATUS_SUCCESS upon successful completion; otherwise it returns a code such as one of the following.
