C++ (Cpp) bkeys_key_get Examples

Example #1

File: keystore.c Project: digiwhite/picocoin

bool bkeys_pubkey_append(struct bp_keystore *ks, const bu160_t *key_id,
			 GString *scriptSig)
{
	struct bp_key key;

		return false;

	free(pubkey);
	
	/* no bp_key_free(&key), as bkeys_key_get() returns a ref */
	return true;
