Name
dlist_ins_prev
Synopsis
int dlist_ins_prev(DList *list, DListElmt *element, const void *data);
Return Value
0 if inserting the element is successful, or -1 otherwise.
Description
Inserts an element just before
element in the doubly-linked list
specified by list. When inserting into
an empty list, element may point
anywhere, but should be NULL to avoid confusion. The new element
contains a pointer to data, so the
memory referenced by data should remain
valid as long as the element remains in the list. It is the
responsibility of the caller to manage the storage associated with
data.
