NAME
tt_default_ptype -- retrieve the current default ptype
SYNOPSIS
#include <Tt/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 fol-
lowing 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The current default process identifier is out of date or invalid.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.
