LDAP_CONTROLS(3) Library Functions Manual LDAP_CONTROLS(3)
ldap_control_create, ldap_control_find, ldap_control_dup,
ldap_controls_dup, ldap_control_free, ldap_controls_free - LDAP
control manipulation routines
OpenLDAP LDAP (libldap, -lldap)
#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);
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.
