Yes, they are using multiple defines. One invokes others when the program is compiled. They're just using one define to invoke a big mess of things.
Remember, they are text replacement. They get called when the program is compiled. Imagine this simpler example:
Code:
#define declare_add(TYPE) type add_##type##(type a, type b) { return(a+b); }
When you use it with, say, int -- it plunks down this text:
Code:
int add_int(int a, int b) { return(a+b); }
...for you to call in your program later.
You are digging far, far, far deeper than needed, IMHO, you already have an example of how to use it. If you want to reverse engineer it from scratch, why not just make a new one?

xo_emit_h
LIBXO(3) BSD Library Functions Manual LIBXO(3)NAME
xo_emit -- emit formatted output based on format string and arguments
LIBRARY
library ``libxo''
SYNOPSIS
#include <libxo/xo.h>
int
xo_emit(const char *fmt, ...);
int
xo_emit_h(xo_handle_t *xop, const char *fmt, ...);
int
xo_emit_hv(xo_handle_t *xop, const char *fmt, va_list vap);
DESCRIPTION
The xo_emit() function emits formatted output using the description in a format string along with a set of zero or more arguments, in a style
similar to printf(3) but using a more complex format description string, as described in xo_format(5).
xo_emit() uses the default output handle, as described in libxo(3), where xo_emit_h() uses an explicit handle. xo_emit_hv() accepts a
va_list for additional flexibility.
