NAMEcsa_list_entries — list the calendar entries that match all the
attribute search criteria
SYNOPSIS
#include <xcsa.h>
CSA_return_code csa_list_entries(
CSA_session_handle session,
CSA_uint32 number_attributes,
CSA_attribute *entry_attributes,
CSA_enum *list_operators,
CSA_uint32 *number_entries,
CSA_entry_handle **entries,
CSA_extension *list_entries_extensions);
DESCRIPTION
The csa_list_entries function lists the entry handles for the calendar
entries that match all the attribute search criteria. Using the
returned entry handles, the entries can have their attributes listed
and read, or the entries can updated or deleted. Only the calendar
owner, users with CSA_OWNER_RIGHTS, users with CSA_VIEW_PUBLIC_ENTRIES,
user with CSA_VIEW_CONFIDENTIAL_ENTRIES, or users with CSA_VIEW_PRI‐
VATE_ENTRIES access rights can list entries in the calendar. If
list_operators is NULL, this specifies a short hand for an array of
operators of CSA_MATCH_EQUAL_TO. The criteria are specified by the
array of attributes and the array of operators. Each operator in oper‐
ators specifies how the corresponding attribute value is to be matched.
The following operators are supported:
CSA_MATCH_ANY
Matches an entry that contains the corresponding attribute
regardless of the value.
CSA_MATCH_EQUAL_TO
Matches an entry that contains an attribute with a value
equal to the corresponding value.
CSA_MATCH_NOT_EQUAL_TO
Matches an entry that contains an attribute with a value not
equal to the corresponding value.
CSA_MATCH_GREATER_THAN
Matches an entry that contains an attribute with a value
greater than the corresponding value.
CSA_MATCH_LESS_THAN
Matches an entry that contains an attribute with a value less
than the corresponding value.
CSA_MATCH_GREATHER_THAN_OR_EQUAL_TO
Matches an entry that contains an attribute with a value
greater than or equal to the corresponding value.
CSA_MATCH_LESS_THAN_OR_EQUAL_TO
Matches an entry that contains an attribute with a value less
than or equal to the corresponding value.
CSA_MATCH_CONTAIN
Applies to character string values only. It matches an entry
that contains the corresponding substring value. The only
operators supported for reminder type attributes are
CSA_MATCH_ANY and CSA_MATCH_EQUAL_TO. Searching of attributes
with opaque data type is not supported. It is implementation
specific in what order the array of entries will be returned.
If either number_attributes is zero or entry_attributes is
NULL, then all of the entries will be returned.
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.
Number Attributes (Uint32)
Specifies the size of the arrays pointed to by entry_attributes and
list_operators. If entry_attributes is NULL, then this must be zero.
Entry Attributes (Attribute)
A pointer to an array of attribute structures specifying the matching
criteria. If number_attributes is zero, then this must be NULL.
List Operators (Enum)
A pointer to an array of matching operators.
List Entries 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 infor‐
mation from the function. A value of NULL indicates that the caller is
not using any extensions. See the extensions structure for more infor‐
mation.
RETURN VALUE
Number Entries (Uint32)
The number of entry handles in entries. If this value is NULL, then no
entries were found to match the search criteria. If more entries were
found than can be represented in the available memory, then the error
CSA_E_INSUFFICIENT_MEMORY will be returned.
Entries (Entry Handle)
A pointer to an array of entry handles that match all the search crite‐
ria. This array is allocated by the service and should be freed with a
single call to csa_free(3).
List Entries 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 func‐
tion succeeded or not, and, if not, why. It may be success or one of
the values listed under ERRORS below.
ERRORS
The csa_list_entries function returns the following error values:
CSA_E_FAILURE
There was a general failure that does not fit the description
of any other error code.
CSA_E_INSUFFICIENT_MEMORY
Insufficient memory was available to complete the requested
operation.
CSA_E_INVALID_ATTRIBUTE
An attribute was specified that was not defined by this spec‐
ification and the implementation does not support the
attribute as an application specific attribute.
CSA_E_INVALID_ATTRIBUTE_VALUE
An invalid attribute value was specified for an attribute.
CSA_E_INVALID_DATA_EXT
The data extension requested is invalid.
CSA_E_INVALID_ENUM
A CSA_enum value is invalid.
CSA_E_INVALID_FLAG
A flag value in the flags argument was invalid.
CSA_E_INVALID_FUNCTION_EXT
The function extension requested is invalid.
CSA_E_INVALID_PARAMETER
A function parameter was invalid.
CSA_E_INVALID_SESSION_HANDLE
The specified Session Handle is invalid or no longer valid
(e.g., after logging off).
CSA_E_NO_AUTHORITY
The user has insufficient authority for this function.
CSA_E_SERVICE_UNAVAILABLE
The requested calendar service is unavailable.
CSA_E_UNSUPPORTED_ATTRIBUTE
An attribute was encountered that is unsupported by the cal‐
endar service.
CSA_E_UNSUPPORTED_DATA_EXT
The data extension requested is not supported.
CSA_E_UNSUPPORTED_ENUM
The specified enumerated value is not valid.
CSA_E_UNSUPPORTED_FLAG
The flag requested is not supported.
CSA_E_UNSUPPORTED_FUNCTION_EXT
The specified function extension is not supported or
CSA_EXT_REQUIRED is set.
