44.7 slapi_vattr_values_get_ex()
Description This function returns the values for an attribute type from an entry, including the
values for any subtypes of the specified attribute type. The routine will return the values of
virtual attributes in that entry if requested to do so.
Syntax
#include "slapi-plugin.h"
int slapi_vattr_values_get_ex(Slapi_Entry *e, char *type,
Slapi_ValueSet*** results, int **type_name_disposition,
char ***actual_type_name, int flags, int *buffer_flags,
int *subtype_count);
Parameters This function takes the following parameters:
Entry from which to get the values.
e
Attribute type name.
type
Pointer to result set.
results
Matching result.
type_name_disposition
Type name as found.
actual_type_name
Bit mask of options. Valid values are as follows:
• SLAPI_REALATTRS_ONLY
• SLAPI_VIRTURALATTRS_ONLY
• SLAPI_VIRTUALATTRS_REQUEST_POINTERS
• SLAPI_VIRTUALATTRS_LIST_OPERATIONAL_ATTRS
flags
Bit mask to be used as input flags for slapi_values_free().buffer_flags
Number of subtypes matched.
subtype_count
Returns This function returns 0 for success, in which case:
• results contains the current values for type all the subtypes in e.
• type_name_disposition contains information on how each type was matched. Valid
values are: SLAPI_VIRTUALATTRS_TYPE_NAME_MATCHED_EXACTLY_OR_ALIAS and
SLAPI_VIRTUALATTRS_TYPE_NAME_MATCHED_SUBTYPE.
• actual_type_name contains the type name as found.
• buffer_flags contains the bit mask to be used as input flags for slapi_values_free().
• subtype_count contains the number of subtypes matched.
Otherwise, this function returns the following:
• SLAPI_VIRTUALATTRS_LOOP_DETECTED (failed to evaluate a vattr).
• SLAPI_VIRTUAL_NOT_FOUND (type not recognized by any vattr and not a real attr in
entry).
• ENOMEM (memory error).
Memory concerns “slapi_vattr_values_free()” should be used to free the returned result set
and type names, passing the buffer_flags value returned from this routine.

44.8 slapi_vattr_values_type_thang_get()
Description This function gets values for an attribute type in the list only if the results field for
that attribute type is NULL. The “slapi_vattr_values_type_thang_get()” function is faster for
getting the values of an attribute when a vattr_type_thang list is returned from a
slapi_vattr_list_types() call. However, when the list for that call returns NULL, the
