ADDCHAIN(3) MBK UTILITY FUNCTIONS ADDCHAIN(3) NAME addchain - create a chain and add it to a list SYNOPSIS #include "mut.h" chain_list *addchain(pthead, ptdata) chain_list *pthead; void *ptdata; PARAMETERS pthead Pointer to a chain_list ptdata Generic pointer to any kind of information DESCRIPTION addchain creates a new chain element and adds it to the front of the list pointed to by pthead, and becomes itself the list head. The chain_lists are mosty used to create temporary lists of homogeneous el- ements, for binary trees, and so on. The ptdata points to any kind of list or may itself be a value, if proper cast is performed at compilation time, and fills the DATA field of the chain structure. For details on the structure, see chain(3). RETURN VALUE addchain returns a pointer to the new head of list. EXAMPLE #include "mut.h" #include "mlo.h" chain_list *get_external_connectors(ptfig) lofig_list *ptfig; { locon_list *pt = ptfig->LOCON; chain_list *c = NULL; /* initialized for regularity */ while (pt) { if (pt->TYPE == EXTERNAL) c = addchain(c, (void *)pt) pt = pt->NEXT; } return c; } SEE ALSO mbk(1), chain(3), freechain(3), delchain(3).
