Get the current status of a thread in the process associated with the file descriptor.
This is a short form of using DCMD_PROC_CURTHREAD to set the current thread, then DCMD_PROC_STATUS to get information about that thread, and then restoring the current thread.
The argument is a pointer to a procfs_status structure (see debug_thread_t in <sys/debug.h>), with the required thread ID specified in the tid field. This structure is filled in with the required information on return. For example:
procfs_status my_status; my_status.tid = 1; devctl( fd, DCMD_PROC_TIDSTATUS, &my_status, sizeof(my_status), NULL);
For more information about the contents of this structure, see "Thread information," earlier in this chapter.
