These routines are used to manipulate structures used for LDAP
ldap_control_create() creates a control with the specified OID using
the contents of the value parameter for the control value, if any.
The content of value is duplicated if dupval is non-zero. The
iscritical parameter must be non-zero for a critical control. The
created control is returned in the ctrlp parameter. The routine
returns LDAP_SUCCESS on success or some other error code on failure.
The content of value, for supported control types, can be prepared
using helpers provided by this implementation of libldap, usually in
the form ldap_create_<control name>_control_value(). Otherwise, it
can be BER-encoded using the functionalities of liblber.
ldap_control_find() searches the NULL-terminated ctrls array for a
control whose OID matches the oid parameter. The routine returns a
pointer to the control if found, NULL otherwise. If the parameter
nextctrlp is not NULL, on return it will point to the next control in
the array, and can be passed to the 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.
ldap_control_dup() duplicates an individual control structure, and
ldap_controls_dup() duplicates a NULL-terminated array of controls.
ldap_control_free() frees an individual control structure, and
ldap_controls_free() frees a NULL-terminated array of controls.
