function retrieves the configuration parameters of the specified service.
| SC_HANDLE hService,
||// handle of service
| LPQUERY_SERVICE_CONFIG lpServiceConfig,
||// address of service config. structure
| DWORD cbBufSize,
||// size of service configuration buffer
| LPDWORD pcbBytesNeeded
||// address of variable for bytes needed
Identifies the service. This handle is returned by the OpenService
function, and it must have SERVICE_QUERY_CONFIG access.
Points to a QUERY_SERVICE_CONFIG
structure in which the service configuration information is returned.
Specifies the size, in bytes, of the buffer pointed to by the lpServiceConfig
Points to a variable that receives the number of bytes needed to return all
the configuration 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 can be set by the service control manager. Others
can be set by the registry functions that are called by the service control
||The specified handle was not opened with SERVICE_QUERY_CONFIG access.
||There is more service configuration information than would fit into the lpServiceConfig buffer. The number of bytes required to get all the information is returned
in the pcbBytesNeeded parameter. Nothing is written to the lpServiceConfig buffer.
||The specified handle is invalid.
function returns the service configuration information kept in the registry
for a particular service. This configuration information was first set via the CreateService
function, and may have been updated via the ChangeServiceConfig
function. If the service was running when the configuration information was
last changed, the information returned with the QueryServiceConfig
will not reflect the true configuration of the service that is running.
Instead, it will reflect the configuration of the service when it is run next. Upon
stopping the service, the service control manager database will be updated with
the configuration that is stored in the registry. The DisplayName key is an
exception to this. When the DisplayName key is changed, it takes effect
immediately regardless of whether the service is running.
