Revision History:
|
|
|
|
10-May-1991 RitaW
|
|
Created routine for wksta APIs.
|
|
24-Jul-1991 JohnRo
|
|
Provide NetpIsServiceStarted() in NetLib for use by <netrpc.h> macros.
|
|
Fixed bug (was using wrong field). Also, this code should use
|
|
NetApiBufferFree() instead of LocalFree().
|
|
16-Sep-1991 JohnRo
|
|
Made changes suggested by PC-LINT.
|
|
18-Feb-1992 RitaW
|
|
Converted to use the Win32 service control APIs.
|
|
06-Mar-1992 JohnRo
|
|
Fixed bug checking current state values.
|
|
02-Nov-1992 JohnRo
|
|
Added NetpIsRemoteServiceStarted().
|
|
30-Jun-1993 JohnRo
|
|
Use NetServiceGetInfo instead of NetServiceControl (much faster).
|
|
Use NetpKdPrint() where possible.
|
|
Use PREFIX_ and FORMAT_ equates.
|
|
Made changes suggested by PC-LINT 5.0
