Deletes the specified element from the stack.
Integer_Type stk_delete_num( Stack_Type stack, Integer_Type N )
The stk_delete_num() routine deletes the given item in the stack. If the element index (N) is not valid then nothng is done, otherwise the element is deleted and the remaining items are shifted back. If successful, this routine returns 0, and non-zero indicates failure.
The stackio module is not available by default; to use it in a S-Lang program, it must be loaded using the S-Lang require() function:
slsh> require("stackio"); slsh> stk_disp( stk ); ------ Stack position: 3 Stack size: 3 Stack allocated: 100 Stack entries: 1 :a.dat: 2 :b.dat: 3 :c.dat: ------ slsh> () = stk_delete_num( stk, 2 ); slsh> stk_disp( stk ) ; ------ Stack position: 2 Stack size: 2 Stack allocated: 100 Stack entries: 1 :a.dat: 2 :c.dat: ------
See the bugs page for the stackio library on the CIAO website for an up-to-date listing of known bugs.
