NAME

       atSetVersAlias, atDelVersAlias, atVno, atGen, atRev - version handling

SYNOPSIS

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

       int     atSetVersAlias (Af_key *aso; char *aliasName);

       int     atDelVersAlias (Af_key *aso; char *aliasName);

       int     atVno (Af_key *aso);

       void    atGen (int versionNumber)

       void    atRev (int versionNumber)

DESCRIPTION

       atSetVersAlias  sets  a version number alias (a unique symbolic name for a version) for aso. The function
       checks, whether aliasName is unique within the ASOs history and complains, if not.  It  returns  TRUE  on
       success  and  FALSE  otherwise.  The  case  that  the version already had the alias name is considered as
       success.

       atDelVersAlias deletes the given aliasName from the list of version aliases attached to aso.  It  returns
       TRUE on success and FALSE otherwise. It also returns TRUE, when the alias name did not exist.

       atVno  returns  a  compact  representation  of  asos generation and revision number, packed into a single
       integer. atGen extracts the generation number, and atRev the revision  number  from  a  versionNumber  in
       compact representation.

DIAGNOSTICS

       On  error,  the  atError  variable  is  set to an appropriate error code, and atErrMsg holds a diagnostic
       message.
