de_free_item()

Frees the data structure created by de_init_item() when it is no longer needed. Returns: NULL.

See also: de_init_item(), de_place_item(), de_set_item_id(), de_set_item_parameters(), de_edit_item(), de_end_edit_item().

Syntax:

de_free_item(itemP);

where

itemP is a pointer to the item structure (the return value of de_init_item() ).

Example:

// Initialize a resistor item
decl itemInfoOSP = de_init_item("R");
// Place the resistor
de_place_item(itemInfoOSP, 0.125, -1.625);
// Free the resistor item
itemInfoOSP = de_free_item(itemInfoOSP);
/* You should set the variable initialized in the de-init_item step to the 
return value of the de_free_item so it resets to NULL. This allows future 
de_place_item()'s with the no longer valid variable to behave as NOPs (not do 
anything). */
