6 addchain - create a chain and add it to a list

9 #include "mut.h"
10 chain_list ∗addchain(pthead, ptdata)
11 chain_list ∗pthead;
12 void ∗ptdata;
13
15 pthead Pointer to a chain_list
16 ptdata Generic pointer to any kind of information
18
20 addchain creates a new chain element and adds it to the front of the
21 list pointed to by pthead, and becomes itself the list head.
22 The chain_lists are mosty used to create temporary lists of homogeneous
23 elements, for binary trees, and so on.
24 The ptdata points to any kind of list or may itself be a value, if
25 proper cast is performed at compilation time, and fills the DATA field
26 of the chain structure. For details on the structure, see chain(3).
27
29 addchain returns a pointer to the new head of list.
