[Raja Saleru]

Hi,
The source file thread_db.h contains the following prototype declarations.
which file contains the definitions for these functions ?

/* Prototypes for exported library functions.  */

/* Initialize the thread debug support library.  */
extern td_err_e td_init (void);

/* Historical relict.  Should not be used anymore.  */
extern td_err_e td_log (void);

/* Generate new thread debug library handle for process PS.  */
extern td_err_e td_ta_new (struct ps_prochandle *__ps, td_thragent_t
**__ta);

/* Free resources allocated for TA.  */
extern td_err_e td_ta_delete (td_thragent_t *__ta);
