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.
