.SH DESCRIPTION
|
|
The routine
|
|
.B ldap_modify_s()
|
|
is used to perform an LDAP modify operation.
|
|
\fIdn\fP is the DN of the entry to modify, and \fImods\fP is a
|
|
null-terminated array of modifications to make to the entry. Each element
|
|
of the \fImods\fP 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

.LP
|
|
The \fImod_op\fP 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 \fImod_type\fP and \fImod_values\fP fields
|
|
specify the attribute type to modify and a null-terminated array of
|
|
values to add, delete, or replace respectively. The \fImod_next\fP
|
|
field is used only by the LDAP server and may be ignored by the
|
|
client.
|
|
.LP
|
|
If you need to specify a non-string value (e.g., to add a
|
|
photo or audio attribute value), you should set \fImod_op\fP to the
|
|
logical OR of the operation as above (e.g., LDAP_MOD_REPLACE)
|
|
and the constant LDAP_MOD_BVALUES. In this case, \fImod_bvalues\fP
|
|
should be used instead of \fImod_values\fP, and it should point to
|
|
a null-terminated array of struct bervals, as defined in <lber.h>.
|
|
.LP
|
|
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 \fImod_values\fP 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.
|
|
.LP
|
|
.B
|
|
ldap_modify_s()
|
|
returns the LDAP error code resulting from the
|
|
modify operation. This code can be interpreted by
|
|
.BR ldap_perror (3)
|
|
and friends.
|
|
.LP
|
|
The
|
|
.B ldap_modify()
|
|
operation works the same way as
|
|
.BR 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
|
|
.BR ldap_result (3).
|
|
.LP
|
|
.B ldap_mods_free()
|
|
can be used to free each element of a NULL-terminated
|
|
array of mod structures. If \fIfreemods\fP is non-zero, the
|
|
\fImods\fP pointer itself is freed as well.
|
|
.SH ERRORS
|
|
.B ldap_modify_s()
|
|
returns an ldap error code, either LDAP_SUCCESS or
|
|
an error if there was trouble.
|
|
.B ldap_modify()
|
|
returns -1 in case
|
|
of trouble, setting the
|
|
.B ld_errno
|
|
field of \fIld\fP.
