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> | |
dbfe9c70 | 32 | .PP |
c67e8ae9 MK |
33 | .B void pthread_kill_other_threads_np(void); |

35 | .SH DESCRIPTION | |
36 | .BR pthread_kill_other_threads_np () | |
33a0ccb2 | 37 | has an effect only in the LinuxThreads threading implementation. |
c67e8ae9 MK |
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 | |

c67e8ae9 | 59 | .SH CONFORMING TO |
047cb380 | 60 | This function is a nonstandard GNU extension; |
0a96a9f0 | 61 | hence the suffix "_np" (nonportable) in the name. |
c67e8ae9 MK |
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). | |

c67e8ae9 MK |
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).) | |
