// PARAMETERS:
// * pszServiceName - the name of the service to be installed
// * pszDisplayName - the display name of the service
// * dwStartType - the service start option. This parameter can be one of
// the following values: SERVICE_AUTO_START, SERVICE_BOOT_START,
// SERVICE_DEMAND_START, SERVICE_DISABLED, SERVICE_SYSTEM_START.
// * pszDependencies - a pointer to a double null-terminated array of null-
// separated names of services or load ordering groups that the system
// must start before this service.
// * pszAccount - the name of the account under which the service runs.
// * pszPassword - the password to the account name.
//
// NOTE: If the function fails to install the service, it prints the error
// in the standard output stream for users to diagnose the problem.
