Question about gnutls_global_set_log_function()

[Murray S. Kucherawy]

I suppose I'm comparing this to the openssl method where there's a
per-thread queue of error codes which can then be translated to
strings.  You might get 0 or 1 back from RSA_verify(), for example,
but if you want detail you have to go into the per-thread error stack,
extract codes, and translate them to strings.

It may be the case that the GNUTLS equivalent functions are more
descriptive.  If that's the case, then I probably don't need this
capability after all.
