THREAD_TERMINATE                     SysV                     THREAD_TERMINATE



NAME
     thread_terminate - initiate thread termination

SYNOPSIS
     include <apollo/thread.h>
     kern_return_t thread_terminate(target_thread)
     thread_t target_thread;


DESCRIPTION
     The thread_terminate call initiates thread termination.  First the call
     unwinds the user stack and looks for cleanup handlers or static
     exceptions.  After the cleanup handlers run, or if there are no cleanup
     handlers found, the thread is removed from the system and the thread id
     is no longer valid.  Note that the target thread must be enabled (inhibit
     count is 0) before termination is initiated.

     The target_thread argument specifies the id of the thread to be
     terminated.

     Data Structures
     The data structures are defined as follows:

     thread_t
          The basic thread id.  This is a black box value that is not
          significant outside the thread system.  It is guaranteed that no two
          active threads on a node will have the same thread id.

     kern_return_t
          An enumeration of the possible values a system call can return.  It
          indicates the success or failure of the call.  It will either be
          [KERN_SUCCESS] to indicate that the call succeeded, or some other
          value to describe the reason for the failure.

DIAGNOSTICS
     Upon successful completion, the thread is killed and thread_terminate
     returns [KERN_SUCCESS]; otherwise, errno is set to indicate the error.

ERRORS
     This function fails if:

     [KERN_INVALID_ARGUMENT]
               The thread id passed in is not valid.

     [KERN_PROTECTION_FAILURE]
               The process this thread is in does not have sufficient rights
               to terminate the target thread.

NOTES
     This call is part of the low level Domain/OS Pthread interface.  Most of
     these calls come directly from the Mach thread interface.  Except as

     noted, they work exactly like the equivalent Mach call; they work between
     processes (the thread id is unique for a node) if the calling process has
     the appropriate rights relative to the target process.

     This call is provided solely for compatibility with the Mach operating
     system. New applications should use the Pthread interface instead.
