<p>The <strong>ldap_modify()</strong> API is an asynchronous request. The
|
||
|
|
result of the operation can be obtained by a subsequent call to <a href=
|
||
|
|
"ldap_result.htm">ldap_result()</a>.</p>
|
||
|
|
|
||
|
|
<p>The <em>mod_op</em> field is used to specify the type of modification to
|
||
|
|
perform and should be one of the following:</p>
|
||
|
|
|
||
|
|
<table width="100%" cellpadding="5">

|

<td valign="top"><strong>LDAP_MOD_DELETE</strong></td>
|

|

|
||
|
|
<tr>
|
||
|
|
<td valign="top"><strong>LDAP_MOD_REPLACE</strong></td>
|
||
|
|
<td valign="top">0x02</td>
|
||
|
|
</tr>
|
||
|
|
</table>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
|
||
|
|
|
||
|
|
<p>This field also indicates the type of values included in the mod_vals union.
|
||
|
|
For binary data, you must also bitwise OR the operation type with <strong>
|
||
|
|
LDAP_MOD_BVALUES</strong> (0x80). This indicates that the values are specified
|
||
|
|
in a NULL-terminated array of struct berval structures. Otherwise, the
|
||
|
|
mod_values will be used (that is, the values are assumed to be a NULL-terminated
|
||
|
|
array of NULL-terminated character strings).</p>
|
||
|
|
|
||
|
|
<p>The <em>mod_type</em> field specifies the name of attribute to add, delete,
|
||
|
|
or replace.</p>
|
||
|
|
|
||
|
|
<p>The <em>mod_vals</em> field specifies a pointer to a NULL-terminated array
|
||
|
|
of values to add, modify or delete respectively. Only one of the mod_values or
|
||
|
|
mod_bvalues variants should be used, with mod_bvalues being selected by ORing
|
||
|
|
the <em>mod_op</em> field with the constant <strong>LDAP_MOD_BVALUES</strong>.
|
||
|
|
<em>mod_values</em> is a NULL-terminated array of NULL-terminated strings and
|
||
|
|
<em>mod_bvalues</em> is a NULL-terminated array of berval structures that can
|
||
|
|
be used to pass binary values such as images.</p>
|
||
|
|
|
||
|
|
<p>For <strong>LDAP_MOD_ADD</strong> modifications, the given values are added
|
||
|
|
to the entry, creating the attribute if necessary.</p>
|
||
|
|
|
||
|
|
<p>For <strong>LDAP_MOD_DELETE</strong> modifications, the given values are
|
||
|
|
deleted from the entry, removing the attribute if no values remain. If the
|
||
|
|
entire attribute is to be deleted, the <em>mod_values</em> field should be set
|
||
|
|
to <strong>NULL</strong>. The server will return an error if the attribute
|
||
|
|
doesn't exist.</p>
|
||
|
|
|
||
|
|
<p>For <strong>LDAP_MOD_REPLACE</strong> modifications, the attribute will have
|
||
|
|
the listed values after the modification, having been created if necessary, or
|
||
|
|
removed if the <em>mod_values</em> field is <strong>NULL</strong>. The server
|
||
|
|
will NOT return an error if the value doesn't exist.</p>
|
||
|
|
|
||
|
|
<p>All modifications are performed in the order in which they are listed.</p>
