how to control Linux mouse cursor movement in C -

-

I'm trying to make an app for the remote control of the mouse on the Linux server via the Android application. As a beginner, I have many problems ... Before writing the Linux server with C, I tried to check whether I can control and move the mouse over Linux according to the code: 

  Include # lt; Unistd.h & gt; #include & lt; String.h & gt; # Include & lt; Stdio.h & gt; # Include & lt; Errno.h & gt; # Include & lt; Fcntl.h & gt; # Include & lt; Stdlib.h & gt; # Include & lt; Sys / stat.h & gt; # Include & lt; Sys / time.h & gt; # Include & lt; Sys / types.h & gt; #include & lt; Linux / input.h & gt; Int main () {struct input_event event, event_end; Int i = 0; Int fd = -1; FD = Open ("/ dev / input / event4", O_RDWR | O_NONBLOCK); If (FD & lt; 0) {mirror ("error"); } Memorandum (& amp; event, 0, size (incident)); Memc (& amp; event, 0, size (event_end)); Gettimeofday (& amp; event.time, NULL); Event.type = EV_REL; Event.code = REL_X; Event.value = 100; Gettimeofday (& amp; event_end.time, NULL); Event_end.type = EV_SYN; Event_end.code = SYN_REPORT; Event_end.value = 0; For (i = 0; i <5; i ++) {Write (FD, and event, size (event)); Write a mouse (fd, and event_and, size (event_end)); Sleep (1); } Closed (FD); Return 0; }

After executing the compile. .. The cursor never moves. Will this be a type of virtualbox setting problem?

Shows the strange strings of the sudo cat / dev / input / event4 symbol when I physically move the mouse over it means that what event 4 is not able to use the mouse cursor movement ?

You can not just write on the device file and expect drivers to send the actual hardware these incidents.

If you are only related to the X Windows environment then you are in luck. You can use this function to send an event to the window:

If you do not know which windows should receive your events, then send it in the root window. Just keep in mind that there is a flag in the events of the X window that shows whether the incident took place from the actual hardware or above. Was synthesized by one of the methods. In most cases, the program only ignores this flag and whether it behaves the same way. But sometimes you may be weird surprises.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
