NAME

       ldap_control_create, ldap_control_find, ldap_control_dup, ldap_controls_dup, ldap_control_free, ldap_controls_free - LDAP control manipula-
       tion 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 con-
       trols, 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.
