| 18 | .SH DESCRIPTION | |
| 19 | .BR pthread_kill_other_threads_np () | |
| 33a0ccb2 | 20 | has an effect only in the LinuxThreads threading implementation. |
| c67e8ae9 MK |
21 | On that implementation, |
| 22 | calling this function causes the immediate termination of | |
| 23 | all threads in the application, | |
| 24 | except the calling thread. | |
| 1f08fc80 | 25 | The cancelation state and cancelation type of the |
| c67e8ae9 MK |
26 | to-be-terminated threads are ignored, |
| 27 | and the cleanup handlers are not called in those threads. | |

| 047cb380 | 48 | This function is a nonstandard GNU extension; |
| 0a96a9f0 | 49 | hence the suffix "_np" (nonportable) in the name. |
| c67e8ae9 MK |
50 | .SH NOTES |
| 51 | .BR pthread_kill_other_threads_np () | |
| 52 | is intended to be called just before a thread calls | |
| 53 | .BR execve (2) | |
| 54 | or a similar function. | |
| 55 | This function is designed to address a limitation in the obsolete | |
| 56 | LinuxThreads implementation whereby the other threads of an application | |
| 57 | are not automatically terminated (as POSIX.1-2001 requires) during | |
| 58 | .BR execve (2). | |
| 847e0d88 | 59 | .PP |

60 | In the NPTL threading implementation, |
| 61 | .BR pthread_kill_other_threads_np () | |
| 62 | exists, but does nothing. | |
| 63 | (Nothing needs to be done, | |
| 64 | because the implementation does the right thing during an | |
| 65 | .BR execve (2).) | |
