]]> ]]> tt_default_session library call tt_default_session retrieve the current default session identifier #include <Tt/tt_c.h> char *tt_default_session The tt_default_session function retrieves the current default session identifier. 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 &cdeman.tt.ptr.error; to extract one of the following Tt_status values from the returned pointer: TT_OK The operation completed successfully. TT_ERR_NOMP The &cdeman.ttsession; process is not running and the ToolTalk service cannot restart it. TT_ERR_PROCID The current default process identifier is out of date or invalid. 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 &cdeman.tt.message.session; to verify that the message was sent in the default session. The application should use &cdeman.tt.free; to free any data stored in the address returned by the ToolTalk API. &cdeman.Tt.tt.c.h;, &cdeman.tt.ptr.error;, &cdeman.tt.free;.
