inviso_rt Direct API to the Inviso Runtime Component

The inviso_rt API is normally only used when programming autostart scripts or similar mechanisms. The reason is that the runtime component is part of the Runtime_tools application and will therefore always be available. But the regular inviso API is part of the Inviso application not necessarily available on the node doing an autostart. It is of course possible to runt a "lean" tracer only using the runtime component manually (i.e not through autostart). The runtime component shall otherwise be controlled through the control component, which is accessed with the inviso API.

 init_tracing(TracerData) -> NodeResult | {error,Reason} Initiate tracing

See inviso:init_tracing/2 for details.

 tp(Mod,Func,Arity,MatchSpec,Opts) -> tp(Mod,Func,Arity,MatchSpec) -> NodeResult | {error,Reason} tp(PatternList) -> NodeResult | {error,Reason} Set global trace patterns Mod,Func = atom() | '_' | ModRegExp | {DirRegExp,ModRegExp}  ModRegExp = regexp_string()  DirRegExp = regexp_string() Arity = int() | '_' MatchSpec = true | false | [] | matchspec() PatternList = [Pattern],  Pattern = {Mod,Func,Arity,MatchSpec,Opts} Opts = [Opt]  Opt = only_loaded NodeResult = {ok,[Ans]} | {error,Reason}   Ans = int() | {error,Reason}

Set global trace patterns. The integer replied if the call was successfull describes the number of matched functions. Using wildcards follows the rules for wildcards of erlang:trace_pattern. It is for instance illegal to specify M=='_' while F is not '_'.

Modules can also be specified using Erlang regular expressions as described in the regexp module. If {DirRegExp,ModRegExp} is used, module selection will further be restricted by that the module must be loaded from a location containing DirRegExp somewhere in the path. This can be used to for instance trace on all modules belonging to a certain application.

 tpl(Mod,Func,Arity,MatchSpec) -> tpl(Mod,Func,Arity,MatchSpec,Opts) -> NodeResult | {error,Reason} tpl(PatternList) -> NodeResult | {error,Reason} Set local trace patterns

NodeResult = {ok,[Ans]} | {error,Reason} Ans = int() | {error,Reason}

Set process trace flags. The integer returned if the call was successful describes the matched number of processes.
