SYNOPSYS¶

#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 elements, 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;
}
