clone2(2) System Calls Manual clone2(2)

clone2, __clone2 - create a child process

Standard C library (libc-lc)

// glibc wrapper:
int __clone2(typeof(int (void *)) *fn,
             void *stack_base, size_t stack_size,
             int flags, void *arg, ...
          /* pid_t *parent_tid, struct user_desc *tls,
             pid_t *child_tid */ );
// System call:
long syscall(SYS_clone2, unsigned long flags, void *stack_base,
            int stack_size,         /* Size of stack */
            int *parent_tid, int *child_tid,
            unsigned long tls);

These interfaces are similar to clone(2) but for ia64.

These interfaces operate in the same way as clone(2), except that stack_base points to the lowest address of the child's stack area, and stack_size specifies the size of the stack pointed to by stack_base.
