NAME

tt_default_ptype − retrieve the current default ptype

SYNOPSIS

#include <tt_c.h> char ∗tt_default_ptype(void);

DESCRIPTION

The tt_default_ptype function retrieves the current default ptype. 

When the application declares a ptype, the ptype becomes the default. 

RETURN VALUE

Upon successful completion, the tt_default_ptype function returns a pointer to a character string that uniquely identifies the current default process type.  If the pointer is NULL, no default ptype 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The current default process identifier is out of date or invalid.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.
