clone2(2)                     System Calls Manual                    clone2(2)

NAME
       clone2, __clone2 - create a child process

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       // 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);

DESCRIPTION
       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.

RETURN VALUE
       See clone(2).

ERRORS
       See clone(2).

STANDARDS
       None.

HISTORY
       Linux (ia64).
