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.
