NAME

LIBRARY

OpenLDAP LDAP (libldap, -lldap)
 

SYNOPSIS

#include <ldap.h>

int ldap_modify(ld, dn, mods)
LDAP *ld;
char *dn;
LDAPMod *mods[];

int ldap_modify_s(ld, dn, mods)
LDAP *ld;
char *dn;
LDAPMod *mods[];

void ldap_mods_free( mods, freemods )
LDAPMod **mods;
int freemods;

DESCRIPTION

        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_modify_s() returns the LDAP error code resulting from the modify operation. This code can be interpreted by ldap_perror(3) and friends.

The ldap_modify() operation works the same way as ldap_modify_s(), except that it is asynchronous, returning the message id of the request it initiates, or -1 on error. The result of the operation can be obtained by calling ldap_result(3).

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.
