Tekkotsu: ProcessID Namespace Reference

Although the ProcessID_t enum specifies the maximum number of processes in its NumProcesses value, this doesn't have to correspond to the actual number of active processes. If you want an element of dynamicism to launch and/or close processes at runtime, simply increase the NumProcesses to a higher value so that space can be allocated for those processes in shared memory regions for things like attachment pointers or other per-process data.


Enumerations
enum	ProcessID_t { MainProcess, MotionProcess, SoundProcess, NumProcesses }
	Holds ID number for each process. More...
Functions
void	setMap (stacktrace::StackFrame idmap[])
	sets location of shared memory map from IDs to current entry point, this is required to be set up before any entry()'s
stacktrace::StackFrame *	getMapFrame ()
	returns the stack frame which should be set to the entry point of the current function
ProcessID_t	getID ()
	returns process's ID number, subject to overriding via setIDHooks()
void	setID (ProcessID_t id)
	sets the ID during init (be careful you know what you're doing if you call this), subject to overriding via setIDHooks()
const char *	getIDStr ()
	returns a string version of the name of the process
Variables
ProcessID_t	ID = NumProcesses
	holds ID number
StackFrame *	frames = NULL
	array of StackFrame structures, one per NumProcesses, set by setMap()

Enumeration Type Documentation

enum ProcessID::ProcessID_t

Holds ID number for each process.

Enumerator:

MainProcess	MainObj process.
MotionProcess	MotoObj process.
SoundProcess	SoundPlay process.
NumProcesses	maximum number of 'friendly' processes -- see class docs

Function Documentation

void ProcessID::setMap ( stacktrace::StackFrame idmap[] )

sets location of shared memory map from IDs to current entry point, this is required to be set up before any entry()'s

Parameters:

idmap

array of StackFrame structures, one per NumProcesses the idea is to have idmap stored in a shared memory region, so functions can tell which one they belong to

Definition at line 39 of file ProcessID.cc.

stacktrace::StackFrame * ProcessID::getMapFrame ( )

returns the stack frame which should be set to the entry point of the current function

this is only valid if it is called before any shared object processing is done

Definition at line 43 of file ProcessID.cc.
