LookupPrivilegeName

The LookupPrivilegeName function retrieves the name corresponding to the privilege represented on a specific system by a specified locally unique identifier (LUID).

BOOL LookupPrivilegeName(
  LPCTSTR lpSystemName,  // system name
  PLUID lpLuid,          // locally unique identifier
  LPTSTR lpName,         // privilege name
  LPDWORD cbName         // displayable name
);

Parameters

lpSystemName

[in] Pointer to a null-terminated string specifying the name of the system on which the privilege name is looked up. If a null string is specified, the function attempts to find the privilege name on the local system.

lpLuid

[in] Pointer to the locally unique identifier by which the privilege is known on the target system.

lpName

[out] Pointer to a buffer that receives a null-terminated string that represents the privilege's name. For example, this string could be "SeSecurityPrivilege".

cbName

[in/out] Pointer to a variable specifying the size, in characters, 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 when the function returns.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is 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.
