Parameters

tokenHandle  IntPtr

An IntPtr pointer handle to the access token that contains the privileges to be modified.

The handle must have AdjustPrivileges access to the token.

If the refPreviousState parameter is not , the handle must also have Query access.

disableAllPrivileges  Boolean

Specifies whether the function disables all of the token's privileges.

If this value is , the function disables all privileges and ignores the refNewState parameter.

If it is , the function modifies privileges based on the information pointed to by the refNewState parameter.

refNewState  TokenPrivileges

A IntPtr pointer to a TokenPrivileges structure that specifies an array of privileges and their attributes.

If the disableAllPrivileges parameter is , the AdjustTokenPrivileges(IntPtr, Boolean, TokenPrivileges, Int32, TokenPrivileges, IntPtr) function enables, disables, or removes these privileges for the token.

bufferLength  Int32

Specifies the size, in bytes, of the buffer pointed to by the refPreviousState parameter.

This parameter can be zero if the refPreviousState parameter is .

refPreviousState  TokenPrivileges

A pointer to a buffer that the function fills with a TokenPrivileges structure that contains the previous state of any privileges that the function modifies.

That is, if a privilege has been modified by this function, the privilege and its previous state are contained in the TokenPrivileges structure referenced by refPreviousState.

If the PrivilegeCount member is 0, then no privileges have been changed by this function.

This parameter can be .

refReturnLength  IntPtr

A pointer to a variable that receives the required size, in bytes, of the buffer pointed to by the refPreviousState parameter.

This parameter can be if refPreviousState is .

Return Value

To determine whether the function adjusted all of the specified privileges, call GetLastWin32Error.
