DESCRIPTION <\/a> <\/h2>\n

Tcl_CallWhenDeleted<\/b> arranges for proc<\/i> to be called by Tcl_DeleteInterp<\/b> if\/when interp<\/i> is deleted at some future time. Proc<\/i> will be invoked just before the interpreter is deleted, but the interpreter will still be valid at the time of the call. Proc<\/i> should have arguments and result that match the type Tcl_InterpDeleteProc<\/b>:<\/p>\n

typedef void Tcl_InterpDeleteProc<\/b>(
ClientData clientData<\/i>,
Tcl_Interp *interp<\/i>);<\/p>\n

The clientData<\/i> and interp<\/i> parameters are copies of the clientData<\/i> and interp<\/i> arguments given to Tcl_CallWhenDeleted<\/b>. Typically, clientData<\/i> points to an application-specific data structure that proc<\/i> uses to perform cleanup when an interpreter is about to go away. Proc<\/i> does not return a value.<\/p>\n

Tcl_DontCallWhenDeleted<\/b> cancels a previous call to Tcl_CallWhenDeleted<\/b> with the same arguments, so that proc<\/i> will not be called after all when interp<\/i> is deleted. If there is no deletion callback that matches interp<\/i>, proc<\/i>, and clientData<\/i> then the call to Tcl_DontCallWhenDeleted<\/b> has no effect.<\/p>\n

Note that if the callback is being used to delete a resource that must<\/i> be released on exit, Tcl_CreateExitHandler<\/b> should be used to ensure that a callback is received even if the application terminates without deleting the interpreter.<\/p>\n
