Uruchomienie, wykonanie: gprof [options] [object_file]
Jak działa GPROF, co robi GPROF: Display the profile data for an object file. The file's symbol table is compared with the call graph profile file gmon.out (previously created by compiling with gcc -pg). Many of gprof's options take a symbol-specification argument, or symspec, to limit the option to specified files or functions. The symspec may be a filename, a function, or a line number. It can also be given as filename:function or filename:linenumber to specify a function or line number in a specific file. gprof expects filenames to contain a period and functions to not contain a period
Dostępne opcje, wywołanie GPROF: Do not display statically declared functions. Since their information might still be relevant, append it to the information about the functions loaded immediately before. Do not display information about each field in the profile.
