NAME

       ldap_get_values, ldap_get_values_len, ldap_count_values - LDAP attribute value handling routines

LIBRARY

       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS

       #include <ldap.h>

       char **ldap_get_values(ld, entry, attr)
       LDAP *ld;
       LDAPMessage *entry;
       char *attr;

       struct berval **ldap_get_values_len(ld, entry, attr)
       LDAP *ld;
       LDAPMessage *entry;
       char *attr;

       int ldap_count_values(vals)
       char **vals;

       int ldap_count_values_len(vals)
       struct berval **vals;

       void ldap_value_free(vals)
       char **vals;

       void ldap_value_free_len(vals)
       struct berval **vals;

DESCRIPTION

       These  routines  are  used  to retrieve and manipulate attribute values from an LDAP entry as returned by
       ldap_first_entry(3) or ldap_next_entry(3).  ldap_get_values() takes the  entry  and  the  attribute  attr
       whose  values  are desired and returns a NULL-terminated array of the attribute's values.  attr may be an
       attribute type as returned from ldap_first_attribute(3) or ldap_next_attribute(3), or  if  the  attribute
       type is known it can simply be given.

       The  number  of  values  in the array can be counted by calling ldap_count_values().  The array of values
       returned can be freed by calling ldap_value_free().

       If the attribute values are binary in nature, and thus not suitable to be returned as an  array  of  char
       *'s,  the  ldap_get_values_len()  routine  can  be  used  instead.   It  takes  the  same  parameters  as
       ldap_get_values(), but returns a NULL-terminated array of pointers to berval structures, each  containing
       the length of and a pointer to a value.

       The number of values in the array can be counted by calling ldap_count_values_len().  The array of values
       returned can be freed by calling ldap_value_free_len().

ERRORS

       If an error occurs in ldap_get_values() or ldap_get_values_len(), NULL is returned and the ld_errno field
       in  the ld parameter is set to indicate the error.  See ldap_error(3) for a description of possible error
       codes.

NOTES

       These routines dynamically allocate memory which the caller must free using the supplied routines.
