DESCRIPTION

These routines perform operations on keyed lists. See the Extended Tcl man page for a description of keyed lists.  

TclX_NewKeyedListObj

Create and initialize a new keyed list object.

Returns:

A pointer to the object.
 

TclX_KeyedListGet


  Retrieve a key value from a keyed list.

Parameters:

o interp - Error message will be return in result if there is an error.
o keylPtr - Keyed list object to get key from.
o key - The name of the key to extract. Will recusively process sub-keys seperated by `.'.
o valueObjPtrPtr - If the key is found, a pointer to the key object
    is returned here.  NULL is returned if the key is not present.

Returns:

o TCL_OK - If the key value was returned.
o TCL_BREAK - If the key was not found.
o TCL_ERROR - If an error occured.
 

TclX_KeyedListSet


  Set a key value in keyed list object.

Parameters:

o interp - Error message will be return in result object.
o keylPtr - Keyed list object to update.
o key - The name of the key to extract. Will recusively process sub-key seperated by `.'.
o valueObjPtr - The value to set for the key.

Returns:


  TCL_OK or TCL_ERROR.
 

TclX_KeyedListDelete


  Delete a key value from keyed list.

Parameters:

o interp - Error message will be return in result if there is an error.
o keylPtr - Keyed list object to update.
o key - The name of the key to extract. Will recusively process sub-key seperated by `.'.

Returns:

o TCL_OK - If the key was deleted.
o TCL_BREAK - If the key was not found.
o TCL_ERROR - If an error occured.
 

TclX_KeyedListGetKeys


  Retrieve a list of keyed list keys.

Parameters:

o interp - Error message will be return in result if there is an error.
o keylPtr - Keyed list object to get key from.
o key - The name of the key to get the sub keys for. NULL or empty to retrieve all top level keys.
o listObjPtrPtr - List object is returned here with key as values.

Returns:

o TCL_OK - If the zero or more key where returned.
o TCL_BREAK - If the key was not found.
o TCL_ERROR - If an error occured.
