How to use trace and dbg in Erlang to debug and trace my program?
The basic steps of tracing for function calls are on a non-live node: > dbg:start(). % start dbg > dbg:tracer(). % start a simple tracer process > dbg:tp(Module, Function, Arity, []). % specify MFA you are interested in > dbg:p(all, c). % trace calls (c) of that MFA for all processes. ... trace here > dbg:stop_clear(). % stop tracer and clear effect of tp and p calls. You can trace for multiple fu

The Erlang BIFs and predefined types. By convention, most Built-In Functions (BIFs) and all predefined types are included in this module. Some of the BIFs and all of the predefined types are viewed more or less as part of the Erlang programming language and are auto-imported. Thus, it is not necessary to specify the module name. For example, the calls atom_to_list(erlang) and erlang:atom_to_list(e
