Yes, this is also a similar approach when using DllCall.

The underscore is also used as a continuation character to tell the interpreter that this line and the next line belong together. This is useful if you have a very long program line and want to be able to see it all on the same screen without turning line wrap on. Below is an example of this, it's entirely pointless to use it in this way with such a short line, but demonstrates its usage.

      hello autoit developers community
      i have some question , i hope to find the answers of it :
      - in large project or even in small ones
      how to make my compiled script use less memory ?
      - how to test my script and be sure that there is no memory leak , or whatsoever reduce my script performance ?
      - where can i find anything talks about autoit script architecture to avoid bad script design ?

      last thing i find these script
      can anyone describe how these scripts work and is these script actually work fine
      thanks

      Disk and Device Read/Write (I/O) Statistics

      This is an example of getting and displaying Read/Write Activity for all Disks and Device I/O.  The actual UDF function _NTQuerySysPerfInfo() returns a whole lot more Performance Information for the computer; however, we are focused on I/O activitiy here.
      This was written as a faster alternative to WMI, as well as an alternative to >Performance Counters (see my >Physical Disk Read/Write activity example).
      Update 2013-07-06:
      Changed: Renamed module
      Changed: _AddCommas now uses a nicer PCRE
      Fixed - Copy and paste errors
      Added - Comma separators

      Network Interface Info, Statistics, and Traffic (incl. IP, TCP, UDP and ICMP)

      This is an example of getting and displaying Network Interface Information, Statistics and Traffic.  Previously this was just a means to getting Network statistics (specifically IP, TCP, UDP, and ICMP), but now it includes Internet Interface information, as well as Interface-specific statistics.
      Since this UDF can be used in different ways, let me cover Statistics first:
      Network Statistics Information

      Stats example output
       
      To retrieve Statistics information, you can call one of the four _Network_xxxxStatistics() functions for IP, TCP, UDP, or ICMP Statistics.  These functions accept 1 argument which specifies which protocol to use.  Basically, zero is IPv4 and non-zero is IPv6.  It defaults to IPv4 if no arguments.  Here's the functions:
      Protocol Statistics Functions: _Network_IPStatistics() -> receives IP statistics _Network_TCPStatistics() -> TCP statistics _Network_UDPStatistics() -> UDP statistics _Network_ICMPStatistics() -> ICMP statistics -
      To get per-interface statistics requires 2 calls.  One call is required to collect information on adapters into an array. Once this information is retrieved, multiple calls to _Network_InterfaceEntryInfo() can be made for each indexed network interface.  Note that _Network_IPv4AdaptersInfo() is the only adapter/interface information function which doesn't get index information - so don't use it unless you want further interface information.  The main UDF functions to use are:
      Network Adapter & Interface Functions: _Network_IPv4AdaptersInfo() -> Retrieves information on Physical IPv4 adapters _Network_IPv4AdaptersInfoEx() -> Retrieves much more info on Physical IPv4 adapters _Network_IPv4AddressTable() -> Retrieves information on IPv4 Interfaces _Network_IPAllAddressTable() -> Retrieves information on both IPv4 and IPv6 interfaces Network Statistics for a Given Interface: _Network_InterfaceEntryInfo() -> For a given interface index, retrieves statistics -
      The simplest way to get overall traffic is to use _Network_IPAllAddressTable() (or _Network_IPv4AddressTable() for IPv4 only) to collect an array of info about interfaces.  This needs to be done only once.  Then, to collect statistics, for each row in the interface array, call _Network_InterfaceEntryInfo() with $aIPAddressTable[$i][0] to get the statistics for that network interface.
      IMPORTANT: Note that for all statistics, the data received/sent are represented as 32-bit numbers, and subject to wraparound after 4GBs of data has been transferred.
      Network Interface Information
      Regarding Network Interface Information, nearly every function except those ending in xxStatistics(), will return various info regarding the network adapters or interfaces.
      Currently, IPv4 and IPv6 addresses are retrieved for the interface, as well as for Gateway, DHCP, DNS and WINS servers (there's some XP issues here as to which functions to use - see UDFs).  The number of IP addresses (since there can be more than one assigned to each interface) is controlled via a parameter $bGetAllIPs.  If this value is non-zero, multiple IP addresses are returned in a string separated by "|" (pipe symbol).
      Also note that the MAC/Physical Address is returned by most functions as well.  These are properly formatted into a hex string in the form "01-23-45-67-89-ab".
      There is one issue with converting IPv6 addresses - on pre-Vista O/S's (Win XP I'm looking at you) WSAStartup must be called by the code.  This is all handled internally, but if you have code that relies on WSAStartup/Cleanup, keep it in mind and let me know if I can better accommodate any potential conflicts.
      Further notes:
      - The TCP Statistics gives information about the number of segments sent/received, rather than the # of packets.  I'm not totally clear on the association, however here's some links:
       What's the difference between a TCP segment and a TCP packet?
       Whats the difference between a Packet, Segment and Frame?
         
      - I'm not sure how segments, packets, or datagrams map to # of bytes, or what API functions I might use to figure this out. Any help there would be appreciated.
      Alternatives:
      While I have opened access to a lot of detailed network and performance information, there are alternatives - check out Netstat (-e for performance stats) or my >Performance Counters UDF's, which has a lot of varied stats (one example of these: >Network Usage).
      Following is the example, included in the ZIP file.  Note there's a cr@pload of info dumped to the console, so you'll probably want to redirect output or copy-and-paste from the output console:

      Updates:
      2013-07-11:
       Changed: _Network_IPv4AdaptersInfoEx() now returns all IP's (if requested) and Address Masks
       Fixed: WSALastError call possible crash with non-array variable
       Changed: _Network_IPAllAddressTable() now allows 'down' status interfaces to be returned
       Added: Some comments on development, info on getting additional stats in the UDF
      2013-07-06:
       Added: Much more Adapter Information
       Changed: Example is now separate from the UDF
       Fixed some minor issues here and there
       Changed: Global Handle to IPHLPAPI.DLL is now contained in the UDF and used to speed up function calls
       Misc. Other fixes I didn't keep track of!
      2013-07-02:
       Hotfix: Ipv6 indexing error
       Fixed: indexing, updated and enhanced output
       Changed: Various functions return arrays even if failure - this is to make XP pre-SP1 and also collection of IPv6 less troublesome. @error should still be checked on return though!
       Added: Adapter and Interface information and statistics collection
      2013-06-20:
       Now covers all the 'p's - IP and ICMP now added

      I took a script written by Beege, optimized the code, and removed the global variables. Its one function, reliable, and very easy to use or modify to your needs. I decided to post it because I found it very hard to find a reliable way to get the cpu percentage of a given process. I know that there are a few different methods but I deem WMI unreliable and everything I tried before optimizing this function was to slow i.e. freezing when other CPU intensive processes were active.
      When monitoring a potentially CPU intensive process, I found it necessary to increase the script's priority otherwise the script/system would freeze which is exactly what I was attempting to prevent!
      See Beege's updated post:
