.SH DESCRIPTION
.LP
These routines provide an interface to the LDAP Content Synchronization 
operation (RFC 4533).
They require an
.BR ldap_sync_t
structure to be set up with parameters required for various phases
of the operation; this includes setting some handlers for special events.
All handlers take a pointer to the \fBldap_sync_t\fP structure as the first
argument, and a pointer to the \fBLDAPMessage\fP structure as received
from the server by the client library, plus, occasionally, other specific
arguments.

The members of the \fBldap_sync_t\fP structure are:
.TP
.BI "char *" ls_base
The search base; by default, the
.B BASE
option in
.BR ldap.conf (5).
.TP
.BI "int " ls_scope
The search scope (one of 
.BR LDAP_SCOPE_BASE ,
.BR LDAP_SCOPE_ONELEVEL ,
.BR LDAP_SCOPE_SUBORDINATE
or
.BR LDAP_SCOPE_SUBTREE ;
see
.B ldap.h
for details).
.TP
.BI "char *" ls_filter
The filter (RFC 4515); by default, 
.BR (objectClass=*) .
.TP
.BI "char **" ls_attrs
The requested attributes; by default
.BR NULL ,
indicating all user attributes.
.TP
.BI "int " ls_timelimit
The requested time limit (in seconds); by default
.BR 0 ,
to indicate no limit.
.TP
.BI "int " ls_sizelimit
The requested size limit (in entries); by default
.BR 0 ,
to indicate no limit.
.TP
.BI "int " ls_timeout
The desired timeout during polling with
.BR ldap_sync_poll (3).
A value of
.BR \-1
means that polling is blocking, so 
.BR ldap_sync_poll (3)
will not return until a message is received; a value of
.BR 0
means that polling returns immediately, no matter if any response
is available or not; a positive value represents the timeout the
.BR ldap_sync_poll (3)
function will wait for response before returning, unless a message
is received; in that case, 
.BR ldap_sync_poll (3)
returns as soon as the message is available.
.TP
.BI "ldap_sync_search_entry_f " ls_search_entry
A function that is called whenever an entry is returned.
The
.BR msg
argument is the
.BR LDAPMessage
that contains the searchResultEntry; it can be parsed using the regular 
client API routines, like 
.BR ldap_get_dn (3),
.BR ldap_first_attribute (3),
and so on.
The
.BR entryUUID
argument contains the entryUUID of the entry.
The
.BR phase
argument indicates the type of operation: one of
.BR LDAP_SYNC_CAPI_PRESENT ,
.BR LDAP_SYNC_CAPI_ADD ,
.BR LDAP_SYNC_CAPI_MODIFY ,
.BR LDAP_SYNC_CAPI_DELETE ;
in case of
.BR LDAP_SYNC_CAPI_PRESENT
or
.BR LDAP_SYNC_CAPI_DELETE ,
only the DN is contained in the 
.IR LDAPMessage ;
in case of 
.BR LDAP_SYNC_CAPI_MODIFY ,
the whole entry is contained in the 
.IR LDAPMessage ,
and the application is responsible of determining the differences
between the new view of the entry provided by the caller and the data
already known.
.TP
.BI "ldap_sync_search_reference_f " ls_search_reference
A function that is called whenever a search reference is returned.
The
.BR msg
argument is the
.BR LDAPMessage
that contains the searchResultReference; it can be parsed using 
the regular client API routines, like 
.BR ldap_parse_reference (3).
.TP
.BI "ldap_sync_intermediate_f " ls_intermediate
A function that is called whenever something relevant occurs during 
the refresh phase of the search, which is marked by
an \fIintermediateResponse\fP message type.
The
.BR msg
argument is the
.BR LDAPMessage
that contains the intermediate response; it can be parsed using 
the regular client API routines, like 
.BR ldap_parse_intermediate (3).
The
.BR syncUUIDs
argument contains an array of UUIDs of the entries that depends
on the value of the
.BR phase
argument.
In case of
.BR LDAP_SYNC_CAPI_PRESENTS ,
the "present" phase is being entered;
this means that the following sequence of results will consist
in entries in "present" sync state.
In case of
.BR LDAP_SYNC_CAPI_DELETES ,
the "deletes" phase is being entered;
this means that the following sequence of results will consist
in entries in "delete" sync state.
In case of
.BR LDAP_SYNC_CAPI_PRESENTS_IDSET ,
the message contains a set of UUIDs of entries that are present;
it replaces a "presents" phase.
In case of
.BR LDAP_SYNC_CAPI_DELETES_IDSET ,
the message contains a set of UUIDs of entries that have been deleted;
it replaces a "deletes" phase.
In case of
.BR LDAP_SYNC_CAPI_DONE,
a "presents" phase with "refreshDone" set to "TRUE" has been returned
to indicate that the refresh phase of refreshAndPersist is over, and
the client should start polling.
Except for the
.BR LDAP_SYNC_CAPI_PRESENTS_IDSET
and
.BR LDAP_SYNC_CAPI_DELETES_IDSET
cases,
.BR syncUUIDs
is NULL.
.BR
.TP
.BI "ldap_sync_search_result_f " ls_search_result
A function that is called whenever a searchResultDone is returned.
In refreshAndPersist this can only occur when the server decides
that the search must be interrupted.
The
.BR msg
argument is the
.BR LDAPMessage
that contains the response; it can be parsed using 
the regular client API routines, like 
.BR ldap_parse_result (3).
The
.BR refreshDeletes
argument is not relevant in this case; it should always be \-1.
.TP
.BI "void *" ls_private
A pointer to private data.  The client may register here
a pointer to data the handlers above may need.
.TP
.BI "LDAP *" ls_ld
A pointer to a LDAP structure that is used to connect to the server.
It is the responsibility of the client to initialize the structure
and to provide appropriate authentication and security in place.

.SH "GENERAL USE"
A
.B ldap_sync_t
structure is initialized by calling
.BR ldap_sync_initialize(3).
This simply clears out the contents of an already existing
.B ldap_sync_t
structure, and sets appropriate values for some members.
After that, the caller is responsible for setting up the
connection (member
.BR ls_ld ),
eventually setting up transport security (TLS),
for binding and any other initialization.
The caller must also fill all the documented search-related fields
of the
.B ldap_sync_t
structure.

At the end of a session, the structure can be cleaned up by calling
.BR ldap_sync_destroy (3),
which takes care of freeing all data assuming it was allocated by
.BR ldap_mem* (3)
routines.
Otherwise, the caller should take care of destroying and zeroing out
the documented search-related fields, and call
.BR ldap_sync_destroy (3)
to free undocumented members set by the API.

.SH "REFRESH ONLY"
The
.BR refreshOnly
functionality is obtained by periodically calling
.BR ldap_sync_init (3)
with mode set to
.BR LDAP_SYNC_REFRESH_ONLY ,
or, which is equivalent, by directly calling
.BR ldap_sync_init_refresh_only (3).
The state of the search, and the consistency of the search parameters,
is preserved across calls by passing the 
.B ldap_sync_t
structure as left by the previous call.

.SH "REFRESH AND PERSIST"
The
.BR refreshAndPersist
functionality is obtained by calling
.BR ldap_sync_init (3)
with mode set to
.BR LDAP_SYNC_REFRESH_AND_PERSIST ,
or, which is equivalent, by directly calling
.BR ldap_sync_init_refresh_and_persist (3)
and, after a successful return, by repeatedly polling with
.BR ldap_sync_poll (3)
according to the desired pattern.

A client may insert a call to 
.BR ldap_sync_poll (3)
into an external loop to check if any modification was returned;
in this case, it might be appropriate to set
.BR ls_timeout
to 0, or to set it to a finite, small value.
Otherwise, if the client's main purpose consists in waiting for
responses, a timeout of \-1 is most suitable, so that the function
only returns after some data has been received and handled.

.SH ERRORS
All routines return any LDAP error resulting from a lower-level error
in the API calls they are based on, or LDAP_SUCCESS in case of success.
.BR ldap_sync_poll (3) 
may return 
.BR LDAP_SYNC_REFRESH_REQUIRED
if a full refresh is requested by the server.
In this case, it is appropriate to call
.BR ldap_sync_init (3)
again, passing the same
.B ldap_sync_t
structure as resulted from any previous call.
