NAME

tt_default_file − return the current default file

SYNOPSIS

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

DESCRIPTION

The tt_default_file() function returns the current default file.

When the application joins a file, the file becomes the default. 

RETURN VALUE

Upon successful completion, the tt_default_file() function returns the pointer to a character string that specifies the current default file. If the pointer is NULL, no default file is set.  The application can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned pointer:

TT_OK
The operation completed successfully.

TT_ERR_NOMP
The ttsession(1) 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The current default process identifier is out of date or invalid.

APPLICATION USAGE

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