The actual code is

#include "httpd.h"
#include "http_config.h"

module MODULE_VAR_EXPORT my_header_module;

static int my_header_fixup(request_rec *r) {
ap_table_set(r->headers_out, "X-My-Header", "this is my header");
return OK;
}

module MODULE_VAR_EXPORT my_header_module = {
STANDARD_MODULE_STUFF,
NULL, /* initializer */
NULL, /* dir config creator */
NULL, /* dir config merger */
NULL, /* server config */
NULL, /* merge server config */
NULL, /* command table */
