4.3 Error handler
=================
The following functions may be used to register handler functions that
are called by Libgcrypt in case certain error conditions occur.
-- Data type: gcry_handler_no_mem_t
This type is defined as: `void (*gcry_handler_no_mem_t) (void *,
size_t, unsigned int)'
-- Function: void gcry_set_outofcore_handler (gcry_handler_no_mem_t
FUNC_NO_MEM, void *CB_DATA)
This function registers FUNC_NO_MEM as `out-of-core handler',
which means that it will be called in the case of not having enough
memory available.
-- Data type: gcry_handler_error_t
This type is defined as: `void (*gcry_handler_error_t) (void *,
int, const char *)'
-- Function: void gcry_set_fatalerror_handler (gcry_handler_error_t
FUNC_ERROR, void *CB_DATA)
This function registers FUNC_ERROR as `error handler', which means
that it will be called in error conditions.
