Let me quote from the manual:
'GCRYCTL_SET_THREAD_CBS; Arguments: struct ath_ops *ath_ops'
This command is obsolete since version 1.6.
in older versions this call was used to register a set of thread
callbacks to use Libgcrypt with different thread implementations. Since
1.6 we only support the standard thread library of the platform;
ie. pthreads on Unix or the standard Windows API.
Your application code needs to implement decryption in another thread
Thake care: A cipher context (e.g. from gcry_cipher_open) may not be
shared between threads.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
