Hi all,
        I need to trace program counter and observe the instruction
call sequence.

application: I need to tranfer a file through ftp and I need to know
what happened during the application running, like which kernel,
filesystem, driver functions are called. Simply I need to store or
collect the program counter sequence from before the application
started to end of the application .So is it possible to store the
program counter sequence in a file for observation?

          If anyone has some words please do put on.

thanking you much

regards
Jaggu
