char **ldap_get_lang_values(LDAP *ld, LDAPMessage *entry,

     const char *target, char **type);

Description

The ldap_get_lang_values() function returns an array of an attribute's string values that matches a specified language subtype. To retrieve the binary data from an attribute, call the ldap_get_lang_values_len() function instead.

ldap_get_lang_values() should be called to retrieve a null-terminated array of an attribute's string values that match a specified language subtype. The entry parameter is the entry retrieved from the directory. The target parameter should contain the attribute type the values that are required, including the optional language subtype. The type parameter points to a buffer that returns the attribute type retrieved by this function. Unlike the ldap_get_values() function, if a language subtype is specified, this function first attempts to find and return values that match that subtype, for example, cn;lang-en.

ldap_get_lang_values_len() returns a null–terminated array of pointers to berval structures, each containing the length and pointer to a binary value of an attribute for a given entry. The entry parameter is the result returned by ldap_result() or ldap_search_s() functions. The target parameter is the attribute returned by the call to ldap_first_attribute() or ldap_next_attribute(), or the attribute as a literal string, such as jpegPhoto or audio.

These functions are deprecated. Use ldap_get_values() or ldap_get_values_len() instead.

Return Values

If successful, ldap_get_lang_values() returns a null-terminated array of the attribute's values. If the call is unsuccessful, or if no such attribute exists in the entry, it returns a NULL and sets the appropriate error code in the LDAP structure.

The ldap_get_lang_values_len() function returns a null-terminated array of pointers to berval structures, which in turn, if successful, contain pointers to the attribute's binary values. If the call is unsuccessful, or if no such attribute exists in the entry, it returns a NULL and sets the appropriate error code in the LDAP structure.
