EXIT_GROUP(2) System Calls Manual EXIT_GROUP(2)

exit_group - exit all threads in a process

Standard C library (libc, -lc)

#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).

This system call terminates all threads in the calling process's thread group.

This system call does not return.

This call is present since Linux 2.5.35.

This call is Linux-specific.

Since glibc 2.3, this is the system call invoked when the _exit(2) wrapper function is called.
