NAME
       inviso_rt_meta - Direct API to the Inviso Runtime Component's meta tracer

DESCRIPTION
       This module provides a direct API to the inviso meta tracer. These functions are only meant to be used in meta tracing CallFunc and Remove-
       Func .

       It can sometimes be necessary to manipulate meta match-patterns from CallFunc s and RemoveFunc s. The problem then is that  call-funcs  and
       remove-funcs are meta trace call-backs executed inside the inviso meta tracer's context. Hence making calls to the regular API's manipulat-
       ing meta trace-patterns will hang the inviso meta tracer!.

       To remedy this problem, a number of useful tpm-functions are available in this API. It must be understood that their actions are  local	to
       the Erlang node where they are called.

EXPORTS
       tpm_ms(Mod,Func,Arity,MSname,MS) -> {ok,0} | {ok,1} | {error,not_initiated}

	      See  inviso:tpm_ms/6  for details. Note that this function only effects meta trace-patterns on the Erlang node where the function is
	      called. This also implies that only the local inviso meta tracer's name-database is updated with MSname .

       tpm_ms_tracer(Mod,Func,Arity,MSname,MS) -> {ok,0} | {ok,1} | {error,not_initiated}

	      See inviso:tpm_ms_ms/6 for details. Note that this function only effects meta trace-patterns on the Erlang node where  the  function
	      is called. This also implies that only the local inviso meta tracer's name-database is updated with MSname .

       list_tpm_ms(Mod,Func,Arity) -> [MSname]

	      Returns  a  list	of all MSname in use for Mod:Func/Arity . This can be useful instead of having to have an own-implemented database
	      over currently in use meta match-functions for a particular function.

       ctpm_ms(Mod,Func,Arity,MSname) -> ok

	      See inviso:ctpm_ms/5 for details. Note that this function only effects meta trace-patterns on the Erlang node where the function	is
	      called. This also implies that only the local inviso meta tracer's name-database is updated with MSname .

       get_tracer() -> Tracer

	      Types  Tracer = pid() | port()

	      Returns  the  pid  or  port  acting  as the receiver of regular trace messages. This is useful if it is necessary to manipulate meta
	      trace-patterns by hand (using erlang:trace_pattern/3 ) and the {tracer,Tracer} must be used in one of the match-function bodies.
