Setting up DWM (Tiling Window Manager)

im trying to setup DWM, im able to successfully patch few patches, but there a couple things im not able figure out 1. im using this on a laptop so i want to bind my volume, brightness, play pause keys which are on the functions keys to be able to control the same. there is Fn button on the keyboard which if pressed with the combination of function keys register as normal function keys and if Fn key is not pressed then function keys act as brightness volume and all. 2. i have everything mostly set up, but there is no status bar in my build, i want to use dwmblocks. but there 3 different patches on suckless.org website and it conflicts with my already patched build for eg there is a line in dwm.c file

if (ev->x > selmon->ww - TEXTW(stext) - getsystraywidth())

and the patch wants me to remove this line -

if (ev->x > selmon->ww - TEXTW(stext))

which i dont have same in my config as im using the systray patch, and wants me to replace with -

if (ev->x > (x = selmon->ww - TEXTW(stext) + lrpad)) {

i dont know if im using the right patch, i want some help with installing the dwmblocks, as i dont want to install someone else's fork i want to configure my own.
