[Valgrind-users] need help on detecting library functions from valgrind output

[Aswin c. <luc...@gm...>]

Hi All,
       I Created a output file foe a executable using
                        tool valgrind --tool=callgrind ./myexecutable
       it is giving library functions also in the ouput i just want to
detect that library functions.Because my objective is see the call graph in
kcachegrind with only functions of my source file. so please help me in
doing this.
                                                                      Thank
you
