  27 .SH NAME
  28 pthread_kill_other_threads_np \- terminate all other threads in process
  29 .SH SYNOPSIS
  30 .nf
  31 .B #include <pthread.h>
  32 .PP
  33 .B void pthread_kill_other_threads_np(void);
  34 .fi
  35 .SH DESCRIPTION
  36 .BR pthread_kill_other_threads_np ()
  37 has an effect only in the LinuxThreads threading implementation.
  38 On that implementation,
  39 calling this function causes the immediate termination of
  40 all threads in the application,
  41 except the calling thread.
  42 The cancellation state and cancellation type of the
  43 to-be-terminated threads are ignored,
  44 and the cleanup handlers are not called in those threads.
  45 .\" .SH VERSIONS
  46 .\" Available since glibc 2.0

  59 .SH CONFORMING TO
  60 This function is a nonstandard GNU extension;
  61 hence the suffix "_np" (nonportable) in the name.
  62 .SH NOTES
  63 .BR pthread_kill_other_threads_np ()
  64 is intended to be called just before a thread calls
  65 .BR execve (2)
  66 or a similar function.
  67 This function is designed to address a limitation in the obsolete
  68 LinuxThreads implementation whereby the other threads of an application
  69 are not automatically terminated (as POSIX.1-2001 requires) during
  70 .BR execve (2).
  71 .PP
  72 In the NPTL threading implementation,
  73 .BR pthread_kill_other_threads_np ()
  74 exists, but does nothing.
  75 (Nothing needs to be done,
  76 because the implementation does the right thing during an
  77 .BR execve (2).)
