Hi List, Before Executing the main function, a startup routine will be executed which will set up the initial environment for the process. This Startup routine will be supplied by the kernel and linked by the Linker. My question is : Can we add one more startup routine before executing the main program, if yes how?? -Vamsi - : send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
