Each process that is running on your box has an entry under proc, look for directories whose name is formed only by numbers under /proc/. For example, /proc/1/ is for init, which has always PID=1. The name of the dir is the PID of the process.

but how can my program read that proc file to extract the information about all processes to display the process id's and their names as like ps command works... please give me some hints as soon as possible

It depends on the language you use. You could check the sources for ps, top or htop and see how they do it. They are simple tools.

now i got the idea what actually proc entry is. i am able to add new file in the proc directory by using create_proc_entry.. i am using this function in writing a kernel module. content of structure is pid and process name of all processes. now i want to write content of this structure into that file named tasklist. how can i do it.
