	* gpgme.texi (Decrypt): Descript gpgme_op_decrypt_result and
	GpgmeDecryptResult.

gpgme
2003-04-28  Marcus Brinkmann  <[email protected]>

	* gpgme.h (struct _gpgme_op_decrypt_result): New structure.
	(GpgmeDecryptResult): New type.
	(gpgme_op_decrypt_result): New prototype.
	* ops.h (_gpgme_op_decrypt_init_result): New prototype.
	(_gpgme_decrypt_status_handler): Fix prototype.
	(_gpgme_decrypt_start): Remove prototype.
	* decrypt-verify.c: Do not include <stdio.h>, <stdlib.h>,
	<string.h> and <assert.h>, "util.h" and "context.h", but
	"gpgme.h".
	(decrypt_verify_status_handler): Change first argument to void *,
	and rework error handling.
	(_gpgme_op_decrypt_verify_start): New function.
	(gpgme_op_decrypt_verify_start): Rewrite using
	_gpgme_op_decrypt_verify_start.
	(gpgme_op_decrypt_verify): Likewise.
	* decrypt.c: Include <string.h>, "gpgme.h" and "util.h".
	(struct decrypt_result): Change to typedef op_data_t, rewritten.
	(is_token): Remove function.
	(release_op_data): New function.
	(skip_token): Remove function.
	(gpgme_op_decrypt_result): New function.
	(_gpgme_decrypt_status_handler): Change first argument to void *.
	Rework error handling.
	(_gpgme_decrypt_start): Rename to ...
	(decrypt_start): ... this.  Call _gpgme_op_decrypt_init_result.
	(_gpgme_op_decrypt_init_result): New function.
	(gpgme_op_decrypt_start): Use decrypt_start.
	(gpgme_op_decrypt): Likewise.
