       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,

       The ldap_modify() and ldap_modify_s() routines are deprecated in favor
       of the ldap_modify_ext() and ldap_modify_ext_s() routines,

       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.
