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.

SEE ALSO
       exit(2)
