NAME
ldap_control_create, ldap_control_find, ldap_control_dup,
ldap_controls_dup, ldap_control_free, ldap_controls_free - LDAP
control manipulation routines
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_control_create(const char *oid, int iscritical, struct
berval *value, int dupval, LDAPControl **ctrlp);
LDAPControl *ldap_control_find( const char *oid, LDAPControl
**ctrls, LDAPControl ***nextctrlp);
LDAPControl *ldap_control_dup(LDAPControl *ctrl);
LDAPControl **ldap_controls_dup(LDAPControl **ctrls);
void ldap_control_free(LDAPControl *ctrl);
void ldap_controls_free(LDAPControl **ctrls);
DESCRIPTION
These routines are used to manipulate structures used for LDAP
controls.
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.
