NAME

       gnutls_srp_set_client_credentials_function - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void            gnutls_srp_set_client_credentials_function(gnutls_srp_client_credentials_t
       cred, gnutls_srp_client_credentials_function         * func);

ARGUMENTS

       gnutls_srp_client_credentials_t         cred
                   is a gnutls_srp_server_credentials_t type.

       gnutls_srp_client_credentials_function         * func
                   is the callback function

DESCRIPTION

       This function can be used to set a callback to retrieve  the  username  and  password  for
       client SRP authentication.  The callback's function form is:

       int (*callback)(gnutls_session_t, char** username, char**password);

       The   username  and   password  must  be  allocated  using gnutls_malloc().   username and
       password should be ASCII strings or UTF-8 strings prepared using the "SASLprep" profile of
       "stringprep".

       The  callback  function will be called once per handshake before the initial hello message
       is sent.

       The callback should not return a negative error code the second  time  called,  since  the
       handshake procedure will be aborted.

       The callback function should return 0 on success.  -1 indicates an error.
