Actually you will see lot of macros defined to achieve small and modular functionality.<br>this makes your code faster to execute but the binary size will be bigger.<br><br>You will see this in kernel code more because we have very low stack area sometime may be one page(4096 bytes) of memory.<br>
automatic variable declare and defined in function will occupy space in stack.<br><br>In application side C expert suggest to have functions because we have very big stack area and function adds readability <br>with easy debugging.<br>
<br>I hope this will help you in your kernel context.<br><br>Thanks,<br>Naveen<br><br><div class="gmail_quote">2011/4/27 Ęsmail Baydan <span dir="ltr"><<a href="mailto:ibaydan@gmail.com">ibaydan@gmail.com</a>></span><br>
