ldap_modify_ext, ldap_modify_ext_s - Perform an LDAP modify operation
OpenLDAP LDAP (libldap, -lldap)
#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 );
The routine ldap_modify_ext_s() is used to perform an LDAP modify
operation. dn is the DN of the entry to modify, and mods is a null-
terminated 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;
struct ldapmod *mod_next;
} 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. The mod_next field is used
only by the LDAP server and may be ignored by the client.
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
modifications, 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
values after the modification, having been created if necessary. All
modifications 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_modify_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,
respectively.
The ldap_modify() and ldap_modify_s() routines are deprecated in
favor of the ldap_modify_ext() and ldap_modify_ext_s() routines,
respectively.
Deprecated interfaces generally remain in the library. The macro
LDAP_DEPRECATED can be defined to a non-zero value (e.g.,
-DLDAP_DEPRECATED=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.
