Hi,
I propose to introduce a data type with the 'free' handler to be actually used
for the 'parameter' of the 'xxkey_info' data .
It will allow the using of non-trivial key parameters,
to be more flexible in pkcs15init when transmitting parameters from supplied
arguments to the libopensc data
(supply from the upper level the data specific free handler or simply to not
free in libopensc the data passed by pointer).
Pkcs15init and pkcs15 functions are in the same libopensc library, but between
them the data are allocated/copied.
(For ex. from 'pkcs15init_keygen_args' to 'pkcs15_prkey_info'.)
There is no immediate necessity of this change (it simply nice) .
I use it in the emulation of pkcs15init for PIV card which hardly will be
committed .
This change can be seen as beginning of future pkcs15init optimization.
So, have you any objections ?
Kind wishes,
Viktor.
