Could you please answer his query. Regards Syed Hi, Why is that the stack size of linux kernel is 8k in 32 bit arch? Whis is this limitation and is there ne way that I can increase the size of the stack?What other alternatives are there in C programming so that I maintain the size of the stack below 8k? Is there ne tool by which I can know to what max extent the stack has reached, so that I can be careful. Thanks in adv. regards Suresh -- Kernelnewbies: Help each other learn about the Linux kernel.
