gnutls_global_set_mem_functions(3)				      gnutls					gnutls_global_set_mem_functions(3)

NAME

       gnutls_global_set_mem_functions - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void  gnutls_global_set_mem_functions(gnutls_alloc_function  alloc_func, gnutls_alloc_function secure_alloc_func, gnutls_is_secure_function
       is_secure_func, gnutls_realloc_function realloc_func, gnutls_free_function free_func);

ARGUMENTS

       gnutls_alloc_function alloc_func
		   it's the default memory allocation function. Like malloc().

       gnutls_alloc_function secure_alloc_func
		   This is the memory allocation function that will be used for sensitive data.

       gnutls_is_secure_function is_secure_func
		   a function that returns 0 if the memory given is not secure. May be NULL.

       gnutls_realloc_function realloc_func
		   A realloc function

       gnutls_free_function free_func
		   The function that frees allocated data. Must accept a NULL pointer.

DESCRIPTION

       This is the function where you set the memory allocation functions gnutls is going to use. By default the libc's allocation functions (mal-
       loc(), free()), are used by gnutls, to allocate both sensitive and not sensitive data.  This function is provided to set the memory alloca-
       tion functions to something other than the defaults

       This function must be called before gnutls_global_init() is called.  This function is not thread safe.

NAME

       gnutls_psk_set_server_credentials_function - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void	 gnutls_psk_set_server_credentials_function(gnutls_psk_server_credentials_t						     cred,
       gnutls_psk_server_credentials_function						  * func);

ARGUMENTS

       gnutls_psk_server_credentials_t						   cred
		   is a gnutls_psk_server_credentials_t structure.

       gnutls_psk_server_credentials_function						  * func
		   is the callback function

DESCRIPTION

       This function can be used to set a callback to retrieve the  user's  PSK  credentials.	The  callback's  function  form  is:  int  (*call-
       back)(gnutls_session_t, const char* username, gnutls_datum_t* key);

	username contains the actual username.	The  key must be filled in using the gnutls_malloc().

       In case the callback returned a negative number then gnutls will assume that the username does not exist.

       The  callback  function	will  only  be called once per handshake.  The callback function should return 0 on success, while -1 indicates an
       error.
