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:
When you use it with, say, int -- it plunks down this text:
...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?

I'm looking for a command which removes files having 0 byte of having only header line (1 line).

xo_destroy
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>
xo_handle_t *
xo_create(unsigned style, unsigned flags);
xo_handle_t *
xo_create_to_file(FILE *fp, unsigned style, unsigned flags);
void
xo_destroy(xo_handle_t *handle);
DESCRIPTION
A libxo handle can be allocated using the xo_create() function.
Example:
xo_handle_t *xop = xo_create(XO_STYLE_JSON, XOF_WARN);
....
xo_emit_h(xop, "testing0);
By default, libxo writes output to standard output. A convenience function is provided for situations when output should be written to a
different file.
Use the XOF_CLOSE_FP flag to trigger a call to fclose(3) for the FILE pointer when the handle is destroyed.
The xo_destroy() function releases a handle and any resources it is using. Calling xo_destroy() with a NULL handle will release any
resources associated with the default handle.
