Learning C while modifying dwm...

I decided to rewrite this out and use this thread for a reference as well as a place to receive any help/guidance (If anyone wishes to) while making modifications to dwm.

bstack.c (Jul. 17. 09)
bstack(Monitor *m) {
       int x, y, h, w, mh;
       unsigned int i, n;
       Client *c;

       for(n = 0, c = nexttiled(m->clients); c; c = nexttiled(c->next), n++);
       if(n == 0)

       c = nexttiled(m->clients);
       mh = m->mfact * m->wh;
       resize(c, m->wx, m->wy, m->ww - 2 * c->bw, (n == 1 ? m->wh : mh) - 2 * c->bw, False);

       if(--n == 0) return;

       x = m->wx;
       y = (m->wy + mh > c->y + c->h) ? c->y + c->h + 2 * c->bw : m->wy + mh;
       w = m->ww / n;
       h = (m->wy + mh > c->y + c->h) ? m->wy + m->wh - y : m->wh - mh;
       if(h < bh)
               h = m->wh;

       for(i = 0, c = nexttiled(c->next); c; c = nexttiled(c->next), i++) {
               resize(c, x, y, ((i + 1 == n) ? m->wx + m->ww - x : w) - 2 * c->bw,
                      h - 2 * c->bw, False);
               if(w != m->ww)
                       x = c->x + WIDTH(c);
P.S. I am writing this here for many reasons, the main reason is I have a bad habit of learning the wrong methods for doing a lot of things (regardless how many times I read books, etc) and since I am learning this all on my own, well, some helpful hints/reading/etc would be...well...helpful...

Anyway, if no one likes that I am doing this, just say so and I will ask a moderator to delete the thread. If you don't mind it, then thanks, ...

Next modification I made...

I added this bit of code to dwm.c
#include <sys/time.h>
#include <time.h>

struct timeval tv;
static time_t curtime;

	gettimeofday(&tv, NULL);
	curtime = tv.tv_sec;  
	strftime(stext, 256, "%d/%m %I:%M %p", localtime(&curtime));
And inside drawbar() I added settime(); right after the initialization of variables. So that whenever the bar is redrawn, the time will be displayed where dwm-5.6 would have normally been displayed. I don't really have a need to keep track of time down to the second, and since opening and closing a window is as simple as a few key presses, it seems to be more appropriate to change the time that way rather than adding extra code that serves no purpose, IMO.

The last thing I changed is I commented out strcpy() and removed the if statement.

updatestatus(void) {
//	if(!gettextprop(root, XA_WM_NAME, stext, sizeof(stext)));
//		strcpy(stext, "dwm-"VERSION);

        gettextprop(root, XA_WM_NAME, stext, sizeof(stext));
So far I don't see any problems.
