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_error(3) to extract one of the following Tt_status values from the returned pointer:

The operation completed successfully.

The ttsession(1) 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 The current default process identifier is out of date or invalid.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_session(3) to verify that the message was sent in the default session.

The application should use tt_free(3) to free any data stored in the address returned by the ToolTalk API.
