Good text program. But I do not understand how to turn it on to record a line in the file?
That operator: function file_open_RW (STRING * filename). I wrote a STRING * filehandle = "Tovar.txt". Accordingly, the main function will be so: file_open_RW (filehandle). But this statement does not create a new file Tovar.txt. And how to use the file_close_RW (when there file type var?) I'm writing so file_close_RW (filehandle), and an error occurs.
