LookupPrivilegeName function
Applies to: desktop apps only
The LookupPrivilegeName function retrieves the name that corresponds to the privilege represented on a specific system by a specified locally unique identifier (LUID).
Syntax
BOOL WINAPI LookupPrivilegeName( __in_opt LPCTSTR lpSystemName, __in PLUID lpLuid, __out_opt LPTSTR lpName, __inout LPDWORD cchName );
Parameters
- lpSystemName [in, optional]
-
A pointer to a null-terminated string that specifies the name of the system on which the privilege name is retrieved. If a null string is specified, the function attempts to find the privilege name on the local system.
- lpLuid [in]
-
A pointer to the LUID by which the privilege is known on the target system.
- lpName [out, optional]
-
A pointer to a buffer that receives a null-terminated string that represents the privilege name. For example, this string could be "SeSecurityPrivilege".
- cchName [in, out]
-
A pointer to a variable that specifies the size, in a TCHAR value, of the lpName buffer. When the function returns, this parameter contains the length of the privilege name, not including the terminating null character. If the buffer pointed to by the lpName parameter is too small, this variable contains the required size.
Return value
If the function succeeds, the function returns nonzero.
If the function fails, it returns zero. To get extended error information, call GetLastError.
Remarks
The LookupPrivilegeName function supports only the privileges specified in the Defined Privileges section of Winnt.h. For a list of values, see Privilege Constants.
