csa_list_entries(3)

NAME
csa_list_entries - list the calendar entries that match all the attribute search criteria

SYNOPSIS
#include <csa.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_PRIVATE_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 operators specifies how the corresponding attribute value is to be matched. The following operators are supported:

    Matches an entry that contains the corresponding attribute regardless of the value.
    Matches an entry that contains an attribute with a value equal to the corresponding value.
    Matches an entry that contains an attribute with a value not equal to the corresponding value.
    Matches an entry that contains an attribute with a value greater than the corresponding value.
    Matches an entry that contains an attribute with a value less than the corresponding value.
    Matches an entry that contains an attribute with a value greater than or equal to the corresponding value.
    Matches an entry that contains an attribute with a value less than or equal to the corresponding value.
    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 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 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 criteria. 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 function 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:

    There was a general failure that does not fit the description of any other error code.
    Insufficient memory was available to complete the requested operation.
    An attribute was specified that was not defined by this specification and the implementation does not support the attribute as an application specific attribute.
    An invalid attribute value was specified for an attribute.
    The data extension requested is invalid.
    A CSA_enum value is invalid.
    A flag value in the flags argument was invalid.
    The function extension requested is invalid.
    A function parameter was invalid.
    The specified Session Handle is invalid or no longer valid (e.g., after logging off).
    The user has insufficient authority for this function.
    The requested calendar service is unavailable.
    An attribute was encountered that is unsupported by the calendar service.
    The data extension requested is not supported.
    The specified enumerated value is not valid.
    The flag requested is not supported.
    The specified function extension is not supported or CSA_EXT_REQUIRED is set.
