"globals" data structure and "port" data structure in wdm sample mouclass

NTDEV
1

hi every1 , there are two data structures globals and port in mouclass.h contained in wdm sample mouclass. can any1 please help me to describe what is their purpose and how does the members it contains for e.g. “ConnectOneClassToOnePort” in global data structure gets intialized i.e how does it gets a value , is it implicit or explicit?. i have read wdm programmign from walter oney and now i am just trying to understand wdm concepts using sample mouclass driver and any help in the context of understanding this mouclass driver will be appreciated as i m feeling saturated while reading the sample.

thank u.

Mouclass is not a great example to start from, but did you do a search in the one and only source file, mouclass.c, for ConnectOneClassToOnePort to see where it is referenced and assigned a value? That will clearly show you what the initial value is, how it changes, and how it gets used.

If you’re just starting, you might want to consider using KMDF instead of
WDM. I would imagine that that sounds unappealing, having just read a WDM
book, but you’ll be able to use all that WDM knowledge with KMDF (as it
wraps WDM), and KMDF is definitely friendlier.

Whether you go with KMDF or WDM, you might want to take a look at ‘toaster’
(src/general/toaster/kmdf OR src/general/toaster/wdm). It’s kind of the
‘tutorial’ WDM/KMDF sample.

Good luck,

mm

@Doron Holan :thanks for the reply…ya i searched in mouclass.h too . there these two structures are defined and in mouclass.c the value in them is tested…but i cant find from where it is initialized a value,actually i have just finished reading some basic concepts on wdm and now i am trying to implement or understand them using a sample …and u just pointed out tat its not a gud sample to start with,tats what i m feeling too…can u suggest smthing using which i can practically learn this concepts and that too in freindly way…

@mm: thanks for the reply,actually i have just finished reading wdm concepts and now i want to learn them in implementation part using a wdm sample…u pointed out to use kmdf sample…right …so i just want to know should switching to kmdf toaster or wdm toaster will ease my task ,and also kmdf toaster will really be better then wdm 1 as i only know wdm concepts,and also i m just a beginner or any other valuable suggestions so that i can learn this concepts using a practical sample and that too in friendly way ?

The kmdf toaster sample would be a better place to start. In fact, look at both the wdm and kmdf versions, you will quickly see which is easier to understand.

Pretty much, and you’ll find that your wdm will very much help with kmdf
too.

Good luck,

That should have read ‘wdm knowledge.’
