Hi Sandeep, probably you want to look at how your program is loaded in memory. For example an ELF binary is understood by ELF format handler inside kernel. Format handler supply their load_binary methods to load a program image im memory and initial its different virtual memory areas (stack, heap etc.). exec system call searches for correct format handler for you based on file header. Please go thoroghly through Understanding the Linux Kernel, 3rd Edition, Chapter 20. Program ExZecution. -Rajat On Fri, May 27, 2011 at 12:14 PM, sandeep kumar <coolsandyforyou@xxxxxxxxx> wrote: > hi all, > I am new to the linux kernel internals.
