DESCRIPTION

These functions use the LDAP display template functions (see
ldap_disptmpl(3LDAP) and ldaptemplates.conf(5)) to produce a plain text
or an HyperText Markup Language (HTML) display of an entry or a set of
values. Typical plain text output produced for an entry might look like:

"Barbara J Jensen, Information Technology Division"
Also Known As:

The exact output produced will depend on the display template
configuration. HTML output is similar to the plain text output, but more
richly formatted.

ldap_entry2text() produces a text representation of entry and writes the
text by calling the writeproc function. All of the attributes values to
be displayed must be present in entry; no interaction with the LDAP
server will be performed within ldap_entry2text. ld is the LDAP pointer
obtained by a previous call to ldap_open. writeproc should be declared
as:

int writeproc( writeparm, p, len )
void *writeparm;
char *p;
int len;

where p is a pointer to text to be written and len is the length of the
text. p is guaranteed to be zero-terminated. Lines of text are
terminated with the string eol. buf is a pointer to a buffer of size
LDAP_DTMPL_BUFSIZ or larger. If buf is NULL then a buffer is allocated
and freed internally. tmpl is a pointer to the display template to be
used (usually obtained by calling ldap_oc2template). If tmpl is NULL, no
template is used and a generic display is produced. defattrs is a NULL-
terminated array of LDAP attribute names which you wish to provide
default values for (only used if entry contains no values for the
attribute). An array of NULL-terminated arrays of default values
corresponding to the attributes should be passed in defvals. The rdncount
parameter is used to limit the number of Distinguished Name (DN)
components that are actually displayed for DN attributes. If rdncount is
zero, all components are shown. opts is used to specify output options.
The only values currently allowed are zero (default output),
LDAP_DISP_OPT_AUTOLABELWIDTH which causes the width for labels to be
determined based on the longest label in tmpl, and
LDAP_DISP_OPT_HTMLBODYONLY. The LDAP_DISP_OPT_HTMLBODYONLY option
instructs the library not to include <HTML>, <HEAD>, <TITLE>, and <BODY>
tags. In other words, an HTML fragment is generated, and the caller is
responsible for prepending and appending the appropriate HTML tags to
construct a correct HTML document.

ldap_entry2text_search() is similar to ldap_entry2text, and all of the
like-named parameters have the same meaning except as noted below. If
base is not NULL, it is the search base to use when executing search
actions. If it is NULL, search action template items are ignored. If
entry is not NULL, it should contain the objectClass attribute values for
the entry to be displayed. If entry is NULL, dn must not be NULL, and
ldap_entry2text_search will retrieve the objectClass values itself by
calling ldap_search_s. ldap_entry2text_search will determine the
appropriate display template to use by calling ldap_oc2template, and will
call ldap_search_s to retrieve any attribute values to be displayed. The
tmpllist parameter is a pointer to the entire list of templates available
(usually obtained by calling ldap_init_templates or
ldap_init_templates_buf). If tmpllist is NULL, ldap_entry2text_search
will attempt to read a load templates from the default template
configuration file ETCDIR/ldaptemplates.conf

ldap_vals2text produces a text representation of a single set of LDAP
attribute values. The ld, buf, writeproc, writeparm, eol, and rdncount
parameters are the same as the like-named parameters for ldap_entry2text.
vals is a NULL-terminated list of values, usually obtained by a call to
ldap_get_values. label is a string shown next to the values (usually a
friendly form of an LDAP attribute name). labelwidth specifies the label
margin, which is the number of blank spaces displayed to the left of the
values. If zero is passed, a default label width is used. syntaxid is a
display template attribute syntax identifier (see ldap_disptmpl(3LDAP)
for a list of the pre-defined LDAP_SYN_... values).

ldap_entry2html produces an HTML representation of entry. It behaves
exactly like ldap_entry2text(3LDAP), except for the formatted output and
the addition of two parameters. urlprefix is the starting text to use
when constructing an LDAP URL. The default is the string ldap:/// The
second additional parameter, base, the search base to use when executing
search actions. If it is NULL, search action template items are ignored.

ldap_entry2html_search behaves exactly like
ldap_entry2text_search(3LDAP), except HTML output is produced and one
additional parameter is required. urlprefix is the starting text to use
when constructing an LDAP URL. The default is the string ldap:///

ldap_vals2html behaves exactly like ldap_vals2text, except HTML output is
produced and one additional parameter is required. urlprefix is the
starting text to use when constructing an LDAP URL. The default is the
string ldap:///

ERRORS

These functions all return an LDAP error code. LDAP_SUCCESS is returned
if no error occurs. See ldap_error(3LDAP) for details. The ld_errno field
of the ld parameter is also set to indicate the error.
