hmm, i got this to work the first time i use the function, the second time always returns 0 for some reason

Code:

int already_there(client *client_list, char *username) {
    if (client_list == NULL) return(0);
    else if (strcmp(client_list->client_name, username)==0) return(1);
    else return already_there(client_list->next, username);
}

libssh2_userauth_password_ex

libssh2_userauth_password_ex(3) 				  libssh2 manual				   libssh2_userauth_password_ex(3)

NAME

       libssh2_userauth_password_ex - authenticate a session with username and password

SYNOPSIS

       #include <libssh2.h>
       int libssh2_userauth_password_ex(LIBSSH2_SESSION *session,
			   const char *username,
			   unsigned int username_len,
			   const char *password,
			   unsigned int password_len,
			   LIBSSH2_PASSWD_CHANGEREQ_FUNC((*passwd_change_cb)));

       #define libssh2_userauth_password(session, username, password) 
	libssh2_userauth_password_ex((session), (username), 
				     strlen(username), 
				     (password), strlen(password), NULL)

DESCRIPTION

       session - Session instance as returned by libssh2_session_init_ex(3)

       username - Name of user to attempt plain password authentication for.

       username_len - Length of username parameter.

       password - Password to use for authenticating username.

       password_len - Length of password parameter.

       passwd_change_cb - If the host accepts authentication but requests that the password be changed, this callback will be issued.  If no call-
       back is defined, but server required password change, authentication will fail.

       Attempt basic password authentication. Note that many SSH servers which appear to support ordinary password authentication actually have it
       disabled and use Keyboard Interactive authentication (routed via PAM or another authentication backed) instead.

RETURN VALUE

       Return 0 on success or negative on failure.  It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
       negative number, it isn't really a failure per se.

ERRORS

       Some of the errors this function may return include:

       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_PASSWORD_EXPIRED -

       IBSSH2_ERROR_AUTHENTICATION_FAILED - failed, invalid username/password or public/private key.
