Module Name:
SvcMap.c (was DanL's OldWrap.c)
Abstract:
These are the API entry points for the NetService API.
These mapping routines implement old-style APIs on new (NT/RPC) machines.
The following functions are in this file:
Exported:
MapServiceControl
MapServiceEnum
MapServiceGetInfo
MapServiceInstall

Revision History:
05-Feb-1992 Danl
Created
30-Mar-1992 JohnRo
Extracted DanL's code from /nt/private project back to NET project.
30-Apr-1992 JohnRo
Use FORMAT_ equates where possible.
14-May-1992 JohnRo
winsvc.h and related file cleanup.
22-May-1992 JohnRo
RAID 9829: winsvc.h and related file cleanup.
02-Jun-1992 JohnRo
RAID 9829: Avoid winsvc.h compiler warnings.
05-Aug-1992 JohnRo
RAID 3021: NetService APIs don't always translate svc names.
(Actually just avoid compiler warnings.)
14-OCt-1992 Danl
Close handles that were left open by using CleanExit.
05-Nov-1992 JohnRo
RAID 7780: netcmd: assertion 'net start' w/ only 2 present services.
Corrected error code for invalid level.

/*++
Routine Description:
This is the DLL entrypoint for NetServiceControl.
Arguments:
servername - Pointer to a string containing the name of the computer
that is to execute the API function.
service - Pointer to a string containing the name of the service
that is to receive the control request.
opcode - The control request code.
arg - An additional (user defined) code that will be passed to the
service.
bufptr - pointer to a location where the service status is to
be returned. If this pointer is invalid, it will be set to NULL
upon return.
Return Value:
The returned InfoStruct2 structure is valid as long as the returned
error is NOT NERR_ServiceNotInstalled or NERR_ServiceBadServiceName.
NERR_Success - The operation was successful.
NERR_InternalError - LocalAlloc or TransactNamedPipe failed, or
TransactNamedPipe returned fewer bytes than expected.
NERR_ServiceNotInstalled - The service record was not found in the
installed list.
NERR_BadServiceName - The service name pointer was NULL.
NERR_ServiceCtlTimeout - The service did not respond with a status
message within the fixed timeout limit (RESPONSE_WAIT_TIMEOUT).
NERR_ServiceKillProcess - The service process had to be killed because
it wouldn't terminate when requested.
NERR_ServiceNotCtrl - The service cannot accept control messages.
The install state indicates that start-up or shut-down is pending.
NERR_ServiceCtlNotValid - The request is not valid for this service.
For instance, a PAUSE request is not valid for a service that
lists itself as NOT_PAUSABLE.
ERROR_ACCESS_DENIED - This is a status response from the service
security check.

client side.

information structure is to be placed.
Return Value:
NERR_Success - The operation was successful.
NERR_ServiceNotInstalled - if the service record was not found in
either the installed or uninstalled lists.

information buffer (SERVICE_INFO_2) is to be placed.
Return Value:
NERR_Success - The operation was successful
NERR_InternalError - There is a bug in this program somewhere.
NERR_ServiceInstalled - The service is already running - we do not
yet allow multiple instances of the same service.
NERR_CfgCompNotFound - The configuration component could not be found.
The Image File could not be found for this service.
NERR_ServiceTableFull - The maximum number of running services has

start-up request within the timeout period. If this was the
only service in the service process, the service process was
killed.
ERROR_NOT_ENOUGH_MEMORY - If this error occurs early in the
start-up procedure, the start-up will fail. If it occurs at the

Routine Description:
This function translates the new-style ServiceStatus structure into
the old-style service info structures. The Info level of the output
structure is stated on entry. Since we cannot obtain PID values from
the new Service Controller, zero is always returned. Since
the new Service Controller will never return text as part of the status,
The text field is always set to NULL.
NOTE:
Since it is possible for this function to get called with
ServiceName and BufPtr pointing to the same location, we must
be careful to not write to the BufPtr location until we have
finished reading all the information from the ServiceStatus
structure.
Arguments:
BufPtr - This is a pointer to a buffer that has already been allocated
for the returned information. The buffer must be of a size that
matches the info level.
ServiceStatus - This is a pointer to the new-style ServiceStatus
structure.
ServiceName - This is a pointer to the service name.
Level - This indicates the desired info level to be output.
DisplayName - If non-NULL, this points to a string that is to be
the internationalized display name for the service.
DestString - This is the buffer where the ServiceName is to be copied.
All info levels require a ServiceName.
