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_request_auth) (void *userdata, const char *realm, int attempt, char *username, char *password); void ne_set_server_auth (ne_session *session, ne_request_auth callback, void *userdata); void ne_set_proxy_auth (ne_session *session, ne_request_auth callback, void *userdata); void ne_forget_auth (ne_session *session); DESCRIPTION
The ne_request_auth function type defines a callback which is invoked when a server or proxy server requires user authentication for a par- ticular request. The realm string is supplied by the server. The attempt is a counter giving the number of times the request has been re- tried 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 con- tain 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 ig- nored. 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); /* ... */ } AUTHOR
