	* gpgme.texi (Waiting For Completion): Adjust doc to changes in
	the code.

gpgme/
2002-02-06  Marcus Brinkmann  <marcus@g10code.de>

	* wait.c (gpgme_wait): Add new argument STATUS, in which the
	status of the returned context is returned.
	(_gpgme_wait_on_condition): Rework the function a bit, to make it
	aware of cancelled processes, and to allow to use gpgme_wait with
	CTX being NULL (as documented in the source).
	(struct proc_s): New member REPORTED.
	* gpgme.h: Fix prototype.
	* verify.c (gpgme_op_verify): Fix use of gpgme_wait.
	* sign.c (gpgme_op_sign):
	* import.c (gpgme_op_import):
	* genkey.c (gpgme_op_genkey):
	* export.c (gpgme_op_export):
	* encrypt.c (gpgme_op_encrypt):
	* delete.c (gpgme_op_delete):

* gpgme_wait accepts a new argument STATUS to return the error status
of the operation on the context. Its definition is closer to
waitpid() now than before.
* The LENGTH argument to gpgme_data_new_from_filepart changed its
type from off_t to the unsigned size_t.

Hey Emacs, this is -*- outline -*- mode!
* ABI's to break:
** The resulting error of an operation can not be retrieved
seperately; the op_foobar operations can't be implemented by the
user, they are not merely convenience, but necessity, while the
op_foobar_start functions for these are unusable (or render the
context unusable, your choice).
** string representation of non-secret keys and ATTR_IS_SECRET is NULL,
which can not be differentiated from the case that it is not
representable.
