X.SH DESCRIPTION
X\fIAf_find\fR and \fIaf_bpfind\fR retrieve ASOs by given attributes.
X\fIAf_find\fR operates on source objects and \fIaf_bpfind\fR only on
Xderived objects.
XThe keys of all found ASOs are returned in \fIresultset\fR.
XThe set is not ordered in any way.
XThe retrieve arguments are passed in \fIattrbuf\fR.
X\fIAttrbuf\fR should be initialized by \fIaf_initattrs\fR before
Xcalling \fIaf_find\fR.
X.LP
XThe structure of \fIattrbuf\fR is the following:
X.nf
X.ta 0.4i 1i 3.2i
Xtypedef struct {
X    char    af_host[MAXHOSTNAMELEN];    /* hostname */
X    char    af_syspath[MAXNAMLEN];    /* system path */
X    char    af_name[MAXNAMLEN];    /* name */
X    char    af_type[MAXTYPLEN];    /* type */
X    int    af_gen;    /* generation number */
X    int    af_rev;    /* revision number */
X    char    af_variant[MAXVARLEN];    /* variant attribute */
X    int    af_state;    /* version state */
X    Af_user    af_owner;    /* owner */
X    Af_user    af_author;    /* author */
X    off_t    af_size;    /* size of file */
X    u_short    af_mode;    /* protection */
X    Af_user    af_locker;    /* locker */
X    time_t    af_mtime;    /* date of last modification */
X    time_t    af_atime;    /* date of last access */
X    time_t    af_ctime;    /* date of last status change*/
X    time_t    af_stime;    /* save date */
X    time_t    af_ltime;    /* date of last lock change */
X    char    *af_udattrs[AF_MAXUDAS];    /* user defined attributes */
X} Af_attrs;
X.fi
X.PP
XA retrieve operation is always limited to one directory.
XIf no syspath is given in the attribute buffer, the current directory
Xis searched.
X.PP
XIt is possible to pass a list of \fIuser defined attributes\fR as
Xretrieve arguments.
XThe list of pointers \fIaf_udattrs\fR in \fIattrbuf\fR can be associated
Xwith strings of the form name[=value].
XThe list must be terminated by a nil pointer.
X.PP
XIt is interpreted in the following way:
X.IP "\fIempty list\fR (first entry is a nil pointer)"
Xmatches every ASO.
X.IP "\fI""""\fR (first entry is an empty string)"
Xmatches every ASO that has \fBno\fR user defined attributes.
X.IP "\fIname\fR[\fI=\fR]"
Xmatches, if a user defined attribute with the given name
Xis present.
X.IP "\fIname=value\fR"
Xmatches all ASOs that have a corresponding user defined
Xattribute, that has at least the given value.
X.PP
XA set generated by \fIaf_find\fR should be released by \fIaf_dropset\fR
Xas soon as it will not be used any longer.
X.PP
X\fIAf_getkey\fR builds up an object key by unique attributes (pathname, name,
Xtype, generation number, revision number and variant name).
XUpon successful completion, the found object key is
Xreturned in the buffer \fIkey\fR. \fIAf_getkey\fR works only on
Xsource objects.
X.PP
XInstead of explicit version numbers, you can pass the pseudo-numbers
X\fIAF_BUSYVERS\fR, \fIAF_FIRSTVERS\fR or \fIAF_LASTVERS\fR to \fIaf_getkey\fR.
X.br
XThe call \fCaf_getkey ("", "otto", "c", AF_BUSYVERS, AF_BUSYVERS)\fR leads
Xto the key of the busy version of the ASO named otto (type c) in
Xyour current context.
X.br
X\fCAf_getkey ("", "otto", "c", AF_LASTVERS, AF_LASTVERS)\fR delivers the
Xlast saved Version (if present).
X.PP
XUse \fIaf_dropkey\fR to free the allocated memory associated with \fIkey\fR.
X.SH SEE ALSO
Xaf_dropset(3)
X.SH DIAGNOSTICS
X\fIAf_find\fR returns the number of found ASOs.
XUpon error, -1 is returned and \fIaf_errno\fR is set to the corresponding
Xerror number.
X.SH BUGS
XA given hostname will be ignored during \fIaf_find\fR.
X.PP
XIn \fIaf_getkey\fR, the \fIvariant\fR argument is ignored.
X.PP
XMixed version numbering in calls of af_getkey
X(eg. \fIgetkey ("", "otto", "c", AF_LASTVERS, 1)\fR or
X\fIgetkey ("", "otto", "c", AF_FIRSTVERS, AF_LASTVERS)\fR are not supported.

X.TH AF_ARCHIVE 5 "" \n(dy.\n(mo.\n(yr
X.SH NAME
Xaf_archive -- format of archive files in the \fIAttribute Filesystem\fR
X.SH SYNOPSIS
X\fB#include <afs.h>
X.br
X#include <afsys.h>
X.SH DESCRIPTION
XAFS archive files are used to store the data and attributes of
Xnon-busy ASOs.
XBeside these, some attributes (including all user defined attributes)
Xof busy ASOs are stored in AFS archive files.
X.PP
XAFS maintains two archive files for each line of development \-
Xone to hold the standard- and the user defined attributes and
Xthe other to hold the data and change notes.
XThese files are stored either in a subdirectory named \fCAFS\fR
Xor in a explicitly named directory somewhere in your file system.
XThe two archive files are named (\(lq\fC^B\fR\(rq stands for \(lqCtrl-B\(rq)
X.br
X    \fC^BA\fR<filename>\fCA\fR        (attributes) and
X.br
X    \fC^BA\fR<filename>\fCD\fR        (data).
X.PP
XThis manual contains a short, exemplary description of the archive structure.
XApart from deltas, all data in AFS-archives are stored as ASCII-strings.
XThe archives contain keywords that have the form \fC^B\fR<key>.
XIn the following description, strings of the form \fI<field>\fR describe
Xthe purpose of the appropriate field in the archive.
