CreateService
[...]
lpBinaryPathName
[in] Pointer to a null-terminated string that contains the fully qualified path to the service binary file. If the path contains a space, it must be quoted so that it is correctly interpreted. For example, "d:\\my share\\myservice.exe" should be specified as "\"d:\\my share\\myservice.exe\"".
The path can also include arguments for an auto-start service. For example, "d:\\myshare\\myservice.exe arg1 arg2". These arguments are passed to the service entry point (typically the main function).
