Parameters

tokenHandle  IntPtr

A handle to an access token from which information is retrieved. If specifies TokenSource, the handle must have access. For all other values, the handle must have access.

tokenInformationClass  TokenInformationClass

Specifies a value from the enumerated type to identify the type of information the function retrieves. Any callers who check the and have it return 0 should also verify that the caller token is not an identify level impersonation token. If the current token is not an app container but is an identity level token, you should return AccessDenied.

tokenInformation  IntPtr

A pointer to a buffer the function fills with the requested information. The structure put into this buffer depends upon the type of information specified by the parameter.

tokenInformationLength  UInt32

Specifies the size, in bytes, of the buffer pointed to by the TokenInformation parameter. If TokenInformation is NULL, this parameter must be zero.

returnLength  UInt32

A pointer to a variable that receives the number of bytes needed for the buffer pointed to by the TokenInformation parameter. If this value is larger than the value specified in the TokenInformationLength parameter, the function fails and stores no data in the buffer.
