SYNOPSIS         top

       #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         top

       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.
