Re: vwait doesn't return after setting TCL_SetVar from a thread

two last questions...
1. if i will use the thread package in the tcl level i will need to do
TCL_ThreadQueue instead of TCL_queue right? how could i tell whay will
be the relevant Q? how to make sure that the event will go to the
relevant thread?

The man page explains the difference. Tcl_ThreadQueueEvent queues new events to
the particular thread in the params. Tcl_QueueEvent queues to the current thread
the function is being called from. Tcl_ThreadQueueEvent only exists when the core
you are using has been compiled for thread support.


2. in your code you have wrapped the TCLEvent pointer with additional
data (TCL_interp pointer) this is your code:

DataReadyEvent *evPtr
.
.
.
Tcl_QueueEvent((Tcl_Event *)evPtr

when i tried to pass similar pointer (with the following structure) with
the same casting.
typedef struct {
Tcl_Event* header;
Tcl_Interp *interp;
TCL_Var2Set Var2set;


} EventData;
the tclsh crushed - if you could elaborate how your conversion was
accepted by the tclsh.


The 'header' should not be a pointer. Should be:

typedef struct {
Tcl_Event header;
Tcl_Interp *interp;
Tcl_Var2Set Var2set;
} EventData;
