Python script: trace and visualize a function call

It's needed a phyton script that tracks a specified function tru its calls till the star/main call in a c project. The project has multiple modules, each of them has moultiple c files having a known namming convention(eg. mod1-main/mod1_main.c, mod2-start/mod2_entry.c, etc). Dummy example: module: mod2-start , file: mod2_entry.c : void mod2_sendByte1ToMain(void) { mod1_receiveByte1(); } void mod2_start(void) { mod2_sendByte1ToMain(); } module: mod2-main , file: mod2_main.c : void mod2_main_call_fct(void) { mod1_call_start(); } module: mod1-main , file: mod1_main.c : void mod1_receiveByte1(void) { // function to track } void mod1_call_start(void) { mod2_start(); } int mod1_main(void) { mod2_main_call_fct(); } This function call track should be loged into a file in plantuml format([login to view URL]). eg. we call the script with a function as an arg: [login to view URL] mod1_receiveByte1 in the log file we should have something like this(this can be your proposal): ------------------------------------------------------------------------------------------------ "mod1-main" -> "mod2-start" : mod2_sendByte1ToMain(void) note left : mod1_receiveByte1 "mod2-start" -> "mod2-start" : mod2_start(void) "mod2-start" -> "mod1-main" : mod1_call_start(void) "mod1-main" -> "mod2-main" : mod2_main_call_fct(void) "mod2-main" -> "mod1-main" : mod1_main(void) ----------------------------------------------------------------------------------------------
