tt_default_session(3) — Subroutines

CDE

NAME

tt_default_session − retrieve the current default session identifier

SYNOPSIS

#include <Tt/tt_c.h> char ∗tt_default_session(void);

DESCRIPTION

The tt_default_session function retrieves the current default session identifier.

RETURN VALUE

Upon successful completion, the tt_default_session function returns the pointer to the unique identifier for the current default session. If the pointer is NULL, no default session is set. The application can use tt_ptr_error3 to extract one of the following Tt_status values from the returned pointer: The operation completed successfully.
The ttsession1 process is not running and the ToolTalk service cannot restart it.
The current default process identifier is out of date or invalid.

APPLICATION USAGE

A session can have more than one session identifier. This means that the application cannot compare the result of tt_default_session with the result of tt_message_session3 to verify that the message was sent in the default session.

The application should use tt_free3 to free any data stored in the address returned by the ToolTalk API.
