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 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 respec-tively. respectively.
       tively.  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  asyn-chronous. asynchronous.
       chronous.  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.

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, 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 inter-faces. interfaces.
       faces.  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.
