NAME

       percept_profile - Percept Collector.

DESCRIPTION

       Percept Collector

       This module provides the user interface for the percept data collection (profiling).

DATA TYPES

         percept_option() = procs | ports | exclusive:

EXPORTS

       start(Filename::string()) -> {ok, Port} | {already_started, Port}

              Equivalent to start(Filename, [procs]).

       start(Filename::string(),  Options::[percept_option()])  -> {ok, Port} | {already_started,
       Port}

              Types:

                 Port = port()

              Starts profiling with supplied options. All events are stored in the file given  by
              Filename. An explicit call to stop/0 is needed to stop profiling.

       start(Filename::string(),     MFA::mfa(),    Options::[percept_option()])    ->    ok    |
       {already_started, Port} | {error, not_started}

              Types:

                 Port = port()

              Starts profiling at the entrypoint specified by the MFA. All events are  collected,
              this  means  that processes outside the scope of the entry-point are also profiled.
              No explicit call to stop/0 is needed, the profiling stops when the  entry  function
              returns.

       stop() -> ok | {error, not_started}

              Stops profiling.
