.SH DESCRIPTION
.sp
.LP
These functions provide a standard way to access LDAP search preference
configuration data.  LDAP search preference configurations are typically used
by LDAP client programs to specify which attributes a user may search by,
labels for the attributes, and LDAP filters and scopes associated with those
searches.  Client software presents these choices to a user, who can then
specify the type of search to be performed.
.sp
.LP
\fBldap_init_searchprefs()\fR reads a sequence of search preference
configurations from a valid LDAP  searchpref configuration file. See
\fBldapsearchprefs.conf\fR(4). Upon success, \fB0\fR is returned and
\fIsolistp\fR is set to point to a list of search preference data structures.
.sp
.LP
\fBldap_init_searchprefs_buf()\fR reads a sequence of search preference
configurations from \fIbuf\fR, whose size is \fIbuflen.\fR \fIbuf\fR should
point to the data in the format defined for an LDAP search preference
configuration file. See  \fBldapsearchprefs.conf\fR(4). Upon success, \fB0\fR
is returned and \fIsolistp\fR is set to point to a list of search preference
data structures.
.sp
.LP
\fBldap_free_searchprefs()\fR disposes of the data structures allocated by
\fBldap_init_searchprefs()\fR.
.sp
.LP
\fBldap_first_searchpref()\fR returns the first search preference data
structure in the list \fIsolist.\fR The \fIsolist\fR is typically obtained by
calling \fBldap_init_searchprefs()\fR.
.sp
.LP
\fBldap_next_searchpref()\fR returns the search preference after \fIso\fR in
the template list \fIsolist.\fR A NULL pointer is returned if \fIso\fR is the
last entry in the list.
