function retrieves the lock status of the specified service control manager
| SC_HANDLE hSCManager,
||// handle of svc. ctrl. mgr. database
| LPQUERY_SERVICE_LOCK_STATUS lpLockStatus,
||// address of lock status structure
| DWORD cbBufSize,
||// size of service configuration buffer
| LPDWORD pcbBytesNeeded
||// address of variable for bytes needed
Identifies the service control manager database. The OpenSCManager
function returns this handle, which must have SC_MANAGER_QUERY_LOCK_STATUS
Points to a QUERY_SERVICE_LOCK_STATUS
structure in which the lock status of the specified database is returned.
Specifies the size, in bytes, of the buffer pointed to by the lpLockStatus
Points to a variable that receives the number of bytes needed to return all
the lock status information.
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
The following error codes may be set by the service control manager. Other
error codes may be set by the registry functions that are called by the service
||The specified handle was not opened with SC_MANAGER_QUERY_LOCK_STATUS access.
||There is more lock status information than would fit into the lpLockStatus buffer. The number of bytes required to get all the information is returned
in the pcbBytesNeeded parameter. Nothing is written to the lpLockStatus buffer.
||The specified handle is invalid.
function returns a QUERY_SERVICE_LOCK_STATUS
structure that indicates whether the specified database is locked. If the
database is locked, the structure provides the account name of the user that holds
the lock and the length of time that the lock has been held.
A process calls the LockServiceDatabase
function to lock a service control manager database and the UnlockServiceDatabase
function to release the lock.
buffer must be large enough to hold the string pointed to by the lpLockOwner
member of the QUERY_SERVICE_LOCK_STATUS
