EXIT_GROUP(2) Linux Programmer's Manual EXIT_GROUP(2)
NAME
exit_group - exit all threads in a process
SYNOPSIS
#include <sys/syscall.h> /* Definition of SYS_* constants */
#include <unistd.h>
noreturn void syscall(SYS_exit_group, int status);
Note: glibc provides no wrapper for exit_group(), necessitating the use of syscall(2).
DESCRIPTION
This system call is equivalent to _exit(2) except that it terminates not only the calling thread, but all threads in the calling process's thread group.
RETURN VALUE
This system call does not return.
VERSIONS
This call is present since Linux 2.5.35.
CONFORMING TO
This call is Linux-specific.
NOTES
Since glibc 2.3, this is the system call invoked when the _exit(2) wrapper function is called.
