csa_query_configurUNIXnSystem V (1 Augucsa_query_configuration(3)
NAME
csa_query_configuration - Determine information about the
installed CSA configuration
SYNOPSIS
#include <csa.h>
CSA_return_code csa_query_configuration(CSA_session_handle session,
CSA_enum item,
CSA_buffer *reference,
CSA_extension *query_configuration_extensions);
DESCRIPTION
The csa_query_configuration() function queries the
underlying implementation's configuration, and returns the
information requested about it, allocating memory when
necessary. The underlying configuration file format is
implementation dependent.
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.
Session may be NULL to indicate that there is no session and
that session independent information should be returned.
This will provide default logon information.
If this value is set to a valid Session Handle, session
dependent configuration information will be returned.
If the session handle is invalid, then the error
CSA_E_INVALID_SESSION_HANDLE is returned.
Item (Enum)
This argument indicates which configuration information
should be returned. If the specified item is not
appropriate for the implementation, the error
CSA_E_UNSUPPORTED_ENUM is returned. The possible values
include:
CSA_CONFIG_CHARACTER_SET
The reference argument will be a pointer to the
array of character set FPI strings for the
implementation. The array will be terminated with
a NULL string. The first character set FPI in the
array is the default character set used if the
caller does not specify one explicitly. This
pointer to the array should be freed using
csa_free(3). This FPI is used by the caller at
Page 1 (printed 9/3/04)
csa_query_configurUNIXnSystem V (1 Augucsa_query_configuration(3)
logon to specify to the implementation to use a
different character set than the default.
CSA_CONFIG_LINE_TERM
The reference argument will be a pointer to a
CSA_enum variable, which will be set to a value of
CSA_LINE_TERM_CRLF
if the line delimiter is a carriage return followed
by a line feed, CSA_LINE_TERM_LF if the line
delimiter is a line feed, or CSA_LINE_TERM_CR if
the line delimiter is a carriage return.
CSA_CONFIG_DEFAULT_SERVICE
The returned reference argument will be a pointer
to a CSA_string into which the default service name
will be returned. A pointer value of NULL will be
written if no default service name is available.
This pointer should be freed using csa_free(3).
This string, along with the one returned by
CSA_CONFIG_DEFAULT_USER, can be used as defaults in
user dialogs when asking for the service name, user
name, and password. This will be returned in the
implementation default character set.
CSA_CONFIG_DEFAULT_USER
The reference argument will be a pointer to a
CSA_string, into which the default user name will
be returned. A pointer value of NULL will be
written if no default user name is available. This
pointer should be freed using csa_free(3). This
string, along with the one returned by
CSA_CONFIG_DEFAULT_SERVICE, can be used as defaults
in user dialogs when asking for the provider name,
user name, and password. This will be returned in
the implementation default character set.
CSA_CONFIG_REQ_PASSWORD
The reference argument will be a pointer to a
CSA_enum variable, which will be set to a value of
CSA_REQUIRED_NO if the password is not required to
logon, CSA_REQUIRED_OPT if the password is optional
to logon, or CSA_REQUIRED_YES if the password is
required to logon.
CSA_CONFIG_REQ_SERVICE
The reference argument will be a pointer to a
CSA_enum variable, which will be set to a value of
CSA_REQUIRED_NO if the service name is not required
to logon, CSA_REQUIRED_OPT if the service name is
optional to logon, or CSA_REQUIRED_YES if the
service name is required to logon.

CSA_CONFIG_REQ_USER
The reference argument will be a pointer to a
CSA_enum variable, which will be set to a value of
CSA_REQUIRED_NO if the user name is not required to
logon, CSA_REQUIRED_OPT if the user name is
optional to logon, or CSA_REQUIRED_YES if the user
name is required to logon.
CSA_CONFIG_UI_AVAIL
The reference argument will be a pointer to a
CSA_boolean variable, which will be set to a true
value if there is UI provided by the CSA
implementation.
CSA_CONFIG_VER_IMPLEM
The reference argument will be a pointer to a
CSA_string variable, which will be set to the CSA
formal public identifier for the version number for
the implementation. This pointer should be freed
using csa_free(3).
CSA_CONFIG_VER_SPEC
The reference argument will be a pointer to a
CSA_string variable, which will be set to the CSA
formal public identifier for the CSA specification
version number supported by this implementation.
This pointer should be freed using csa_free(3).
The error CSA_E_UNSUPPORTED_ENUM is returned if the
specified value is not supported by the implementation.
Query Configuration 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.
Through extensions, the application can find out which
extensions are available. The extension to do this is
CSA_X_COM_SUPPORT_EXT. Any CSA implementation that supports
extensions must support this extension. For more
information on this extension, see the common extensions
section of the extensions appendix in this document
RETURN VALUE
Reference (Buffer)
This argument points to the buffer in which to receive the
configuration information. The type of the variable or
buffer depends on the item argument.

Query Configuration 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_query_configuration() 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_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_NOT_SUPPORTED
The operation requested is not supported by this
implementation.
CSA_E_SERVICE_UNAVAILABLE
The requested calendar service is unavailable.
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.
