extern int x1f4_slip_shuffle
    (void *subtext, void *context);

The x1f4_slip_shuffle function executes the next instruction of the program for which the subtext step by step execution context was created in the context execution context.

See Procedural Program Execution.

See x1f4_head_shuffle.

See x1f4_tail_shuffle.

If successful, the function returns 0. Non zero is returned for failure.

Note that program execution logic defines no failure conditions other than memory allocation failure and expression evaluation failure, the later defining in turn no failure conditions other than function or operator evaluation failure.

The context evaluation context is passed as the first argument to function and operator logic evaluation routines. It is otherwise not interpreted.
