NAME
ldap_modify_ext, ldap_modify_ext_s - Perform an LDAP modify operation
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_modify_ext(
LDAP *ld,
char *dn,
LDAPMod *mods[],
LDAPControl **sctrls,
LDAPControl **cctrls,
int *msgidp );
int ldap_modify_ext_s(
LDAP *ld,
char *dn,
LDAPMod *mods[],
LDAPControl **sctrls,
LDAPControl **cctrls );
void ldap_mods_free(
LDAPMod **mods,
int freemods );
DESCRIPTION
The routine ldap_modify_ext_s() is used to perform an LDAP modify oper-
ation. dn is the DN of the entry to modify, and mods is a null-termi-
nated array of modifications to make to the entry. Each element of the
mods array is a pointer to an LDAPMod structure, which is defined
below.
typedef struct ldapmod {
int mod_op;
char *mod_type;
union {
char **modv_strvals;
struct berval **modv_bvals;
} mod_vals;
} LDAPMod;
#define mod_values mod_vals.modv_strvals
#define mod_bvalues mod_vals.modv_bvals
The mod_op field is used to specify the type of modification to perform
and should be one of LDAP_MOD_ADD, LDAP_MOD_DELETE, or
LDAP_MOD_REPLACE. The mod_type and mod_values fields specify the
attribute type to modify and a null-terminated array of values to add,
delete, or replace respectively.
If you need to specify a non-string value (e.g., to add a photo or
audio attribute value), you should set mod_op to the logical OR of the
operation as above (e.g., LDAP_MOD_REPLACE) and the constant
LDAP_MOD_BVALUES. In this case, mod_bvalues should be used instead of
mod_values, and it should point to a null-terminated array of struct
bervals, as defined in <lber.h>.
For LDAP_MOD_ADD modifications, the given values are added to the
entry, creating the attribute if necessary. For LDAP_MOD_DELETE modi-
fications, the given values are deleted from the entry, removing the
attribute if no values remain. If the entire attribute is to be
deleted, the mod_values field should be set to NULL. For
LDAP_MOD_REPLACE modifications, the attribute will have the listed val-
ues after the modification, having been created if necessary. All mod-
ifications are performed in the order in which they are listed.
ldap_mods_free() can be used to free each element of a NULL-terminated
array of mod structures. If freemods is non-zero, the mods pointer
itself is freed as well.
ldap_modify_ext_s() returns a code indicating success or, in the case
of failure, indicating the nature of the failure. See ldap_error(3)
for details
The ldap_modify_ext() operation works the same way as ldap_mod-
ify_ext_s(), except that it is asynchronous. The integer that msgidp
points to is set to the message id of the modify request. The result
of the operation can be obtained by calling ldap_result(3).
Both ldap_modify_ext() and ldap_modify_ext_s() allows server and client
controls to be passed in via the sctrls and cctrls parameters, respec-
tively.
DEPRECATED INTERFACES
The ldap_modify() and ldap_modify_s() routines are deprecated in favor
of the ldap_modify_ext() and ldap_modify_ext_s() routines, respec-
tively.
Deprecated interfaces generally remain in the library. The macro
LDAP_DEPRECATED can be defined to a non-zero value (e.g., -DLDAP_DEPRE-
CATED=1) when compiling program designed to use deprecated interfaces.
It is recommended that developers writing new programs, or updating old
programs, avoid use of deprecated interfaces. Over time, it is
expected that documentation (and, eventually, support) for deprecated
interfaces to be eliminated.
