I need to delete a TTY in my AIX 4.3 system. I have tried using the smit but everytime I try it, there is a message telling me that the device is in use and cannot be changed. How do I take the device "offline", so to speak, so that I can edit the settings and/or delete it.

pthread_cancel
PTHREAD_CANCEL(3) BSD Library Functions Manual PTHREAD_CANCEL(3)
NAME
pthread_cancel -- cancel execution of a thread
SYNOPSIS
#include <pthread.h>
int
pthread_cancel(pthread_t thread);
DESCRIPTION
The pthread_cancel() function requests that thread be canceled. The target thread's cancelability state and type determines when the cancel-
lation takes effect. When the cancellation is acted on, the cancellation cleanup handlers for thread are called. When the last cancellation
cleanup handler returns, the thread-specific data destructor functions will be called for thread. When the last destructor function returns,
thread will be terminated.
The cancellation processing in the target thread runs asynchronously with respect to the calling thread returning from pthread_cancel().
A status of PTHREAD_CANCELED is made available to any threads joining with the target. The symbolic constant PTHREAD_CANCELED expands to a
constant expression of type (void *), whose value matches no pointer to an object in memory nor the value NULL.
RETURN VALUES
If successful, the pthread_cancel() functions will return zero. Otherwise an error number will be returned to indicate the error.
ERRORS
The pthread_cancel() function will fail if:
[ESRCH] No thread could be found corresponding to that specified by the given thread ID.
SEE ALSO
pthread_cleanup_pop(3), pthread_cleanup_push(3), pthread_exit(3), pthread_join(3), pthread_setcancelstate(3), pthread_setcanceltype(3),
pthread_testcancel(3)
STANDARDS
The pthread_cancel() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
AUTHORS
This manual page was written by David Leonard <d@openbsd.org> for the OpenBSD implementation of pthread_cancel().
