i have a linked list set up like
typedef struct client_list {
char *client_name;
int client_socket_fd;
struct client_list *next;
} client;
client *client_list=NULL;
before adding to the list i check if it already exists, only if it does not then i add
if (client_list==NULL... (1 Reply)
can someone provide an example of a struct linked list, where it has strings as its values, and then how do I check if a specific string (say called buffer) exists in the list of structs?
i dont understand how to make a copy of it to check with
this is what i have

Hi, I am programming in kernel, and I want to use a double linked list that holds infos that every process could access and modify THIS list. So, I suppose it is a 'global' variable since every process(thread) can reach it, I am wondering where to put it? by changing some of the kernel files? (1 Reply)

ne_forget_auth
NE_SET_SERVER_AUTH(3) neon API reference NE_SET_SERVER_AUTH(3)NAME
ne_set_server_auth, ne_set_proxy_auth, ne_forget_auth - register authentication callbacks
SYNOPSIS
#include <ne_auth.h>
typedef int (*ne_auth_creds)(void *userdata, const char *realm, int attempt, char *username, char *password);
void ne_set_server_auth(ne_session *session, ne_auth_creds callback, void *userdata);
void ne_set_proxy_auth(ne_session *session, ne_auth_creds callback, void *userdata);
void ne_forget_auth(ne_session *session);
DESCRIPTION
The ne_auth_creds function type defines a callback which is invoked when a server or proxy server requires user authentication for a
particular request. The realm string is supplied by the server. The attempt is a counter giving the number of times the request has been
retried with different authentication credentials. The first time the callback is invoked for a particular request, attempt will be zero.
To retry the request using new authentication credentials, the callback should return zero, and the username and password buffers must
contain NUL-terminated strings. The NE_ABUFSIZ constant gives the size of these buffers.
Tip
If you only wish to allow the user one attempt to enter credentials, use the value of the attempt parameter as the return value of the
callback.
To abort the request, the callback should return a non-zero value; in which case the contents of the username and password buffers are
ignored.
The ne_forget_auth function can be used to discard the cached authentication credentials.
EXAMPLES
/* Function which prompts for a line of user input: */
extern char *prompt_for(const char *prompt);
static int
my_auth(void *userdata, const char *realm, int attempts,
char *username, char *password)
{
strncpy(username, prompt_for("Username: "), NE_ABUFSIZ);
strncpy(password, prompt_for("Password: "), NE_ABUFSIZ);
return attempts;
}
int main(...)
{
ne_session *sess = ne_session_create(...);
ne_set_server_auth(sess, my_auth, NULL);
/* ... */
}
