Hi, is there any example mod_slotmem codes that we can understand the
usage? Or could you give me an usage example? For example we are using
apr_shm_create() in post_config, but mod_slotmem is a little bit hard to
understand i think.
And i want to ask a question,
is it a problem to create
typedef struct node {
ELEMENT node_element;
struct node *left;
struct node *right;
}NODE;
kind of struct. A struct that has two struct elements. As i mentioned
before what i'm trying to implement is a binary tree as a data structure.
regards
