4 * i3 - an improved dynamic tiling window manager

7 * A "match" is a data structure which acts like a mask or expression to match
8 * certain windows or not. For example, when using commands, you can specify a
9 * command like this: [title="*Firefox*"] kill. The title member of the match
10 * data structure will then be filled and i3 will check each window using
11 * match_matches_window() to find the windows affected by this command.
18 * Initializes the Match data structure. This function is necessary because the
19 * members representing boolean values (like dock) need to be initialized with
23 void match_init(Match *match) {
24 memset(match, 0, sizeof(Match));
29 * Check if a match is empty. This is necessary while parsing commands to see
30 * whether the user specified a match at all.

35 * TAILQ and I don’t want to start with things like assuming that the
36 * last member of a struct really is at the end in memory… */
