Mailboxes and Mailers provide a way to authenticate when the URL does not
contain enough information. The default action is to call function
@code{auth_authenticate} who will get the @emph{user} and @emph{passwd}
if not set, this function can be override by a custom method.
@deftypefun int auth_create (auth_t *@var{pauth}, void *@var{owner})
@end deftypefun
@deftypefun void auth_destroy (auth_t *@var{pauth}, void *@var{owner})
@end deftypefun
@deftypefun int auth_prologue (auth_t @var{auth})
@end deftypefun
@deftypefun int auth_authenticate (auth_t @var{auth}, char **@var{user}, char **@var{passwd})
@end deftypefun
@deftypefun int auth_epilogue (auth_t @var{auth})
@end deftypefun
A simple example of an authenticate function:
@example
#include <mailutils/auth.h>
#include <stdio.h>
#include <string.h>
int
my_authenticate (auth_t auth, char **user, char **passwd)
@{
char u[128] = "";
char p[128] = "";
/* prompt the user name */
printf ("User: ");
fflush (stdout);
fgets (u, sizeof (u), stdin);
u[strlen (u) - 1] = '\0'; /* nuke the trailing NL */
/* prompt the passwd */
printf ("Passwd: "); fflush (stdout);
echo_off ();
fgets (p, sizeof(p), stdin);
echo_on ();
p[strlen (p) - 1] = '\0';
/* duplicate */
*user = strdup (u);
*passwd = strdup (p);
return 0;
