I can able to read barcode manually in a gedit. i Need to create a c
program which reads the barcode device and write the data to a text file.
How this can be done.
If gedit is getting the bar code data, then most probably it's a keyboard
mimic.
Do you want to write a command line application in C or a GUI based one?
If it is command line based, just use stdin or whatever you use
to normally get keyboard input.
If it's GUI based, either you can wait for keyboard events or the simpler
way is to ask the user to place the cursor in a text field and then scan.
Then collect the information form the text field.
