SYNOPSIS
#include <Tt/tt_c.h>
char *tt_default_ptype(void)DESCRIPTION
The tt_default_ptype function retrieves the current default ptype.

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 ser‐
vice cannot restart it.

The current default process identifier is out of date or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.
