.SH DESCRIPTION
These functions use the LDAP display template routines (see
ldap_disptmpl(3) and ldap_templates.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:
.nf

    "Barbara J Jensen, Information Technology Division"
     Also Known As:
		   Babs Jensen
		   Barbara Jensen
		   Barbara J Jensen
     E-Mail Address:
		   [e-mail]
     Work Address: 
		   535 W. William 
		   Ann Arbor, MI 48103
     Title:        
		   Mythical Manager, Research Systems
     ...
.fi
The exact output produced will depend on the display template configuration.
HTML output is similar to the plain text output, but more richly formatted.
.LP
.B ldap_entry2text(\|)
produces a text representation of
.I entry
and writes the text by calling the
.I writeproc
function.  All of the attributes values to be displayed must be present
in
.I entry;
no interaction with the LDAP server will be performed within
.B ldap_entry2text.
.I ld 
is the LDAP pointer obtained by a previous call to
.B ldap_open.
.I writeproc
should be declared as:
.LP
.ft B
.nf
int writeproc( writeparm, p, len )
.ft
	void		*writeparm;
	char		*p;
	int		len;
.fi
.LP
where
.I p
is a pointer to text to be written and
.I len
is the length of the text.
.I p
is guaranteed to be zero-terminated.  Lines of text are terminated
with the string
.I eol.
.I buf
is a pointer to a buffer of size
.B LDAP_DTMPL_BUFSIZ
or larger.  If
.I buf is
.B NULL
then a buffer is allocated and freed internally.
.I tmpl
is a pointer to the display template to be used (usually obtained by calling
.B ldap_oc2template).
If
.I tmpl
is NULL,
no template is used and a generic display is produced.
.I defattrs
is a NULL-terminated array of LDAP attribute names which you wish to
provide default values for (only used if
.I entry
contains no values for the attribute).  An array of NULL-terminated arrays of
default values corresponding to the attributes should be passed in
.I defvals.  The
.I rdncount
parameter is used to limit the number of Distinguished Name (DN) components
that are actually displayed for DN attributes.  If
.I rdncount
is zero, all components are shown.
.I opts
is used to specify output options.  The only values currently allowed
are zero (default output),
.B LDAP_DISP_OPT_AUTOLABELWIDTH
which causes the width for labels to be determined based on the longest
label in
.I tmpl, and
.B LDAP_DISP_OPT_HTMLBODYONLY.
The 
.B 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.
.LP
.B ldap_entry2text_search(\|)
is similar to
.B ldap_entry2text,
and all of the like-named parameters have the same meaning except as noted
below.  
If
.I 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
.I entry
is not NULL, it should contain the
.I objectClass
attribute values for the entry to be displayed.  If
.I entry
is NULL,
.I dn
must not be NULL, and 
.B ldap_entry2text_search
will retrieve the objectClass values itself by calling
.B ldap_search_s.
.B ldap_entry2text_search
will determine the appropriate display template to use by calling
.B ldap_oc2template,
and will call
.B ldap_search_s
to retrieve any attribute values to be displayed.  The
.I tmpllist
parameter is a pointer to the entire list of templates available (usually
obtained by calling
.B ldap_init_templates
or
.B ldap_init_templates_buf).
If
.I tmpllist
is NULL,
.B ldap_entry2text_search
will attempt to read a load templates from the default template configuration
file ETCDIR/ldaptemplates.conf.
.LP
.B ldap_vals2text
produces a text representation of a single set of LDAP attribute values.  The
.I ld,
.I buf,
.I writeproc,
.I writeparm,
.I eol,
and
.I rdncount
parameters are the same as the like-named parameters for
.B ldap_entry2text.
.I vals
is a NULL-terminated list of values, usually obtained by a call to
.B ldap_get_values.
.I label
is a string shown next to the values (usually a friendly form of an
LDAP attribute name).
.I 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.
.I syntaxid
is a display template attribute syntax identifier (see ldap_disptmpl(3)
for a list of the pre-defined 
.B LDAP_SYN_...
values).
.LP
.B ldap_entry2html
produces an HTML representation of 
.I entry.
It behaves exactly like ldap_entry2text(3), except for the formatted output
and the addition of two parameters.
.I urlprefix
is the starting text to use when constructing an LDAP URL.  The default is
the string
.I ldap:///
The second additional parameter,
.I base,
the search base to use when executing search actions.  If it is NULL, search
action template items are ignored.
.LP
.B ldap_entry2html_search
behaves exactly like ldap_entry2text_search(3), except HTML output is produced
and one additional parameter is required.
.I urlprefix
is the starting text to use when constructing an LDAP URL.  The default is
the string
.I ldap:///
.LP
.B ldap_vals2html
behaves exactly like ldap_vals2text, except HTML output is produced
and one additional parameter is required.
.I urlprefix
is the starting text to use when constructing an LDAP URL.  The default is
the string
.I ldap:///
.SH ERRORS
These routines all return an LDAP error code (LDAP_SUCCESS is returned
if no error occurs).  See ldap_error(3) for details. The
.I ld_errno
field of the
.I ld
parameter is also set to indicate the error.
