.SH DESCRIPTION
|
|
These routines are used to manipulate structures used for LDAP controls.
|
|
|
|
.BR ldap_control_create ()
|
|
creates a control with the specified
|
|
.I OID
|
|
using the contents of the
|
|
.I value
|
|
parameter for the control value, if any. The content of
|
|
.I value
|
|
is duplicated if
|
|
.I dupval
|
|
is non-zero. The
|
|
.I iscritical
|
|
parameter must be non-zero for a critical control. The created control
|
|
is returned in the
|
|
.I ctrlp
|
|
parameter. The routine returns
|
|
.B LDAP_SUCCESS
|
|
on success or some other error code on failure.
|
|
The content of
|
|
.IR value ,
|
|
for supported control types, can be prepared using helpers provided
|
|
by this implementation of libldap, usually in the form
|
|
.BR "ldap_create_<control name>_control_value" ().
|
|
Otherwise, it can be BER-encoded using the functionalities of liblber.
|
|
|
|
.BR ldap_control_find ()
|
|
searches the NULL-terminated
|
|
.I ctrls
|
|
array for a control whose OID matches the
|
|
.I oid
|
|
parameter. The routine returns a pointer to the control if found,
|
|
NULL otherwise.
|
|
If the parameter
|
|
.I nextctrlp
|
|
is not NULL, on return it will point to the next control
|
|
in the array, and can be passed to the
|
|
.BR ldap_control_find ()
|
|
routine for subsequent calls, to find further occurrences of the same
|
|
control type.
|
|
The use of this function is discouraged; the recommended way of handling
|
|
controls in responses consists in going through the array of controls,
|
|
dealing with each of them in the returned order, since it could matter.
|
|
|
|
.BR ldap_control_dup ()
|
|
duplicates an individual control structure, and
|
|
.BR ldap_controls_dup ()
|
|
duplicates a NULL-terminated array of controls.
|
|
|
|
.BR ldap_control_free ()
|
|
frees an individual control structure, and
|
|
.BR ldap_controls_free ()
|
|
frees a NULL-terminated array of controls.
