gnutls_global_set_mem_functions and GNUTLS_E_MEMORY_ERROR

[Dmitry Antipov]

Hello,

1) Why gnutls_global_set_mem_functions is obsolete?

2) What if an application tends to handle memory-related errors by using it's 
own
   malloc/realloc/free wrappers instead of checking for GNUTLS_E_MEMORY_ERROR?

3) Is it legal to write:

   gnutls_malloc = my_malloc;
   gnutls_realloc = my_realloc;
   gnutls_calloc = my_calloc;
   gnutls_free = my_free;
   gnutls_strdup = my_strdup;

   in attempt to be compatible with gnutls < 3.3.0?

Thanks in advance,
Dmitry
