NAME

       atSetComment, atUnlock - log and lock handling

SYNOPSIS

       #include <atfs.h>
       #include <atfstk.h>

       int atSetComment (Af_key *aso, int commentType, char *commentText, int mode);

       int atUnlock (Af_key *aso);

DESCRIPTION

       atSetComment sets a comment attribute for the attributed software object aso. Valid commentTypes are

       AT_COMMENT_INTENT
		   for expressing a change intent describing planned modifications.

       AT_COMMENT_DESCR
		   for issuing a descriptive text expressing the purpose of the document.

       AT_COMMENT_LOG
		   for writing a change log describing the changes made.

       With  the  argument  commentText,  a default text may be given.	According to the mode (see below), the user will be asked for entering the
       comment attribute value. When a default text is given, this will be offered for modification. With an commentText argument, the previous of
       the according comment attribute is taken as default text.

       With the mode field, the behavior of atSetComment can be influenced. Three flags may me set:

       AT_FROMSTDIN
		   advises atSetComment to read the user input from standard input, otherwise an editor will be started.

       AT_REUSE    causes reuse of the comment text expressed during the previous invocation of atSetComment, if there was any.

       AT_CONFIRM  lets  the  user  confirm,  that an comment shall be expressed.  Otherwise, atSetComment asks for the comment text without prior
		   confirmation. This flag is ignored, when AT_FROMSTDIN is set and the change comment is taken from standard input.

       atUnlock unlocks aso by calling af_unlock (manual page af_lock(3)). If a change intent was previously set for aso, this will be eliminated.

DIAGNOSTICS

       atSetComment and atUnlock return FALSE (zero) on error. Additionally, the atError variable is set and afErrMsg holds a diagnostic message.

ENVIRONMENT

       EDITOR - the default editor to be called.
