char* buf;
buf = (char*) malloc(1024);
HDF* hdf;
CSPARSE* cs;
hdf_init(&hdf);
hdf_set_value(hdf, \"name\", \"foo\"); 
cs_init(&cs, hdf);
strcpy(buf, \"This is <?cs var:name ?>\");
cs_parse_string(cs, buf, 1024);
cs_render(cs, NULL , func);

NEOERR*
func(void *b, char* a)
{
    printf(\"%s\", a);
}

This is<space>

strcpy(buf, \"<?cs var:name ?>\");
