TD_THR_DBSUSPEND 3C_DB "Oct 20, 1998"
NAME
td_thr_dbsuspend, td_thr_dbresume - suspend and resume threads in libc_db
SYNOPSIS

cc [ flag... ] file... -lc_db [ library... ]
#include <proc_service.h>
#include <thread_db.h>

td_err_e td_thr_dbsuspend(const td_thrhandle_t *th_p);

td_err_e td_thr_dbresume(const td_thrhandle_t *th_p);
DESCRIPTION

These operations do nothing other than call ps_lstop(3PROC) and ps_lcontinue(3PROC), respectively, on the lightweight process (LWP) identified by the thread handle, th_p. Since ps_lstop() and ps_lcontinue() must be provided by the caller's application (see proc_service(3PROC)), and the application (a debugger-like entity) has full control over the stopped state of the process and all of its LWPs, td_thr_dbsuspend() and td_thr_dbresume() are unnecessary interfaces. They exist only to maintain interface compatibility with the past.

RETURN VALUES
TD_OK

The call completed successfully.

TD_BADTH

An invalid thread handle was passed in.

TD_DBERR

A call to ps_lstop() or ps_lcontinue() failed.

TD_ERR

A libc_db internal error occurred.
