SYNOPSIS

#include &<xcsa.h>
CSA_return_code csa_list_entry_attributes(
CSA_session_handle session,
CSA_entry_handle entry,
CSA_uint32 *number_names,
CSA_attribute_reference **entry_attributes_names,
CSA_extension *list_entry_attributes_extensions);

DESCRIPTION

The csa_list_entry_attributes function lists the names of the entry attributes associated with a calendar entry. Using the returned entry attributes name(s), the attributes value(s) may be read using the csa_read_entry_attributes(3) function.

ARGUMENTS

Session (Session Handle)

Opaque session handle that represents a session with the calendaring service.

Session handles are created by a logon function call and invalidated with a logoff function call. If the session handle is invalid, then the error CSA_E_INVALID_SESSION_HANDLE is returned.

Entry (Entry Handle)

Specifies the handle of the calendar entry that will have its attributes listed. If the entry handle is invalid, then the error CSA_E_INVALID_ENTRY_HANDLE is returned.

List Entry Attributes Extensions (Extension)

A pointer to an array of CSA_extension structures for this function. The array may contain both input extensions for providing additional information to the function and output extensions for receiving information from the function. A value of NULL indicates that the caller is not using any extensions. See the extensions structure for more information.

RETURN VALUE

Number Names (Uint32)

A pointer to the number of attribute names returned in entry_attribute_names.

Entry Attribute Names (Attribute Reference)

A pointer to an array of attribute references containing the names of the entry attributes in the calendar entry. This array is allocated by the service, and should be freed with a single call to csa_free(3).

List Entry Attributes Extensions (Extension)

If output extensions were passed to the function in the extensions list, the results from the service will be available in the extension. See the extensions structure for more information. Whether the function succeeded or not, and, if not, why. It may be success or one of the values listed under ERRORS below.
