Hello, I use the boost graph library (Version 1.33.1 of Boost) for my programming task. I wanted to profile my program with gprof. I compilated the source code with the -pg option and linked it also with that option. Now I'm examining the output file of gprof. Some functions of boost graph library are not explicitly listed there althogh I use them. These functions are: vertices() add_edge() What I see instead are some complicated functions. I have copied them here from my gprof-Output. But where are vertices() and add_edge()? Or are they meant by these complicated functions.
