gnutls_srp_set_client_credentials_function - API function
#include <gnutls/gnutls.h>
void gnutls_srp_set_client_credentials_function(gnutls_srp_client_credentials_t cred, gnutls_srp_client_credentials_function * func);
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().
The username should be an ASCII string or UTF-8 string. In case of a UTF-8 string it is recommended to be following the PRECIS framework for usernames (rfc8265). The password can be in ASCII format, or normalized using gnutls_utf8_password_normalize().
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.
