how do I implement the following to make the compilation warnings go
away?
$ cat readMDF.vala
/*valac --pkg gio-2.0 gio-sample.vala*/
int main (string[] args) {
// A reference to our file
var file = File.new_for_path (args[1]);
if (!file.query_exists ()) {
stderr.printf ("File '%s' doesn't exist.\n", file.get_path ());
return 1;
}
try {
// Open file for reading and wrap returned FileInputStream into a
// DataInputStream, so we can read line by line
var dis = new DataInputStream (file.read ());
string line;
// Read lines until end of file (null) is reached
while ((line = dis.read_line (null)) != null) {
// stdout.printf ("%s\n", line);
// foreach(var field in line.split("|")){
// stdout.printf ("%s\n", field);
// }
var fieldAry = line.split("|");
int i = 0;
while(i<fieldAry.length){
stdout.printf ("%6d%60s\n", i, fieldAry[i].strip());
i++;
}
// foreach(string fl in fieldAry) {
// string as = fl.to_string();
// stdout.printf ("%60s\n", as.strip());
// }
}
} catch (Error e) {
error ("%s", e.message);
}
return 0;
}
