   • How does a SHX-file work?

     Top Answer

     Answered Jan 27, 2009 · 6 votes

     According to the spec the shx contains a 100 byte header followed by a sequence of 8 byte records. Each record stores a 4 byte offset and a 4 byte content length for a record in the main .shp data file.

     +-----------------------------------------------+| header (100 bytes) |+-----------------+------------------+----------+| offset(4 bytes) | length (4 bytes) | +-----------------+------------------+| offset(4 bytes) | length (4 bytes) | +-----------------+------------------+| offset(4 bytes) | length (4 bytes) | +-----------------+------------------+| offset(4 bytes) | length (4 bytes) | +-----------------+------------------+| .... | +-----------------+------------------+

     Note that the offset is specified in 16 bit words, so the offset for the first record is 50 (as the .shp header is 100 bytes, or 50 words, long). The content length is also specified in 16 bit words.

     So, you can figure out the number of records from (index_file_length-100)/8, and use the index to access a particular shape record in the .shp file at random or in sequence.

   • How does a microsoft batch file work?

     Top Answer

     Answered Jun 19, 2009 · 2 votes

     It's entirely interpreted as slow as can be. A program (command-line processor) interprets each line one at a time, figures out what it wants to do, does it, and either checks the next line or goes where it's told to go.

     However, since a batch file can invoke the assistance of COM dlls (which are essentially compiled programs), whatever is done within those can be very efficient. And there are thousands of dlls with chunks of functionality like database access, use interface components, and most everything you'd need to build many difficult but conventional things.

   • How does a .json file work in a API call?

     Top Answer

     Answered May 23, 2017 · 1 votes

     JSON is just a format of your data, that you can then use, for example in JavaScript.

     It is back-end language independent. By this I mean, that front-end of the application does not care who produced .json file.

     Maybe it was Java application, maybe it was Python, or PHP application it does not matter. It can be also static file, with fixed content which just has json format.

     After you receive such thing in front-end, you can do with it whatever you want. From your perspective it will be probably some kind of nested array.

     In example you provided, I get:

     {"errors":[{"code":215,"message":"Bad Authentication data."}]}

     And it is fine, it's just data you get. It is JSON format - that is true. But you don't care that path has .json in the URL, it could have any extension, what is important is what's inside.

     That is a beauty of JSON. You can prepare for yourself static file with mocked data in JSON format, and use it while developing front-end of the application. When you wish, you can have back-end application which will return real data for your app.

     You can also see here, how to return json file from PHP: Returning JSON from a PHP Script

   • How does editing a remote file work?

     Top Answer

     Answered Apr 17, 2013 · 0 votes

     The application would download the whole file locally, open it, make changes and upload the whole file again. A classic example is WinSCP where you can 'edit' a remote file. The application (WinSCP) knows which protocol to use (FTP/FTPS/SFTP etc) and knows the parameters to be used (e.g. remote directory to upload the file to, username, password, port etc). Even if a file is large the whole file must be downloaded in order to me modified.

     There appears to be no way of doing partial file updates in FTP, SFTP. HTTP or SCP. Infact there is no well known open source protocol to do this. If there is an implementation out there it has to proprietary.

   • How does a FILE pointer in C work?

     Top Answer

     Answered Jun 20, 2020 · 16 votes

     The file pointer p is pointing a structure handled by the C library that manages I/O functionality for the named file in the given open mode.

     You can't tell, a priori, whether what it points at is statically allocated memory or dynamically allocated memory; you don't need to know. You treat it as an opaque pointer.

     Note that the standard says:

     ISO/IEC 9899:2011 7.21.3 Files

     The address of the FILE object used to control a stream may be significant; a copy of a FILE object need not serve in place of the original.

     This says (roughly): Don't futz around with the pointer; pass it to the functions that need it and otherwise leave well alone.

   with open(torrentfilename, 'rb') as torrentfile:

    Sep 21, 2016 · BitTorrent is a peer-to-peer protocol, which means that the computers in a BitTorrent "swarm" (a group of computers downloading and uploading the same torrent) transfer data between each other without the need for a central server. Traditionally, a computer joins a BitTorrent swarm by loading a .torrent file into a BitTorrent client.
