NAME
pthreadkillotherthreadsnp - terminate all other threads in process SYNOPSIS
#include
void pthreadkillotherthreadsnp(void); DESCRIPTION pthreadkillotherthreadsnp() has an effect only in the LinuxThreads threading implementation. On that implementation, calling this func‐ tion causes the immediate termination of all threads in the applica‐ tion, except the calling thread. The cancellation state and cancella‐ tion type of the to-be-terminated threads are ignored, and the cleanup handlers are not called in those threads. ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├────────────────────────────────┼───────────────┼─────────┤

NOTES pthreadkillotherthreadsnp() is intended to be called just before a thread calls execve(2) or a similar function. This function is designed to address a limitation in the obsolete LinuxThreads implemen‐ tation whereby the other threads of an application are not automati‐
cally terminated (as POSIX.1-2001 requires) during execve(2). In the NPTL threading implementation, pthreadkillotherthreadsnp() exists, but does nothing. (Nothing needs to be done, because the implementation does the right thing during an execve(2).)
