Things like this likely being ended up with typo. How about this? (not tested)
#define __PRINT_ATTR(fmt, cast, field) \
fprintf(fp, " %-28s "fmt"\n", #field, cast attr->field)
#define PRINT_ATTR(field) __PRINT_ATTR("%u", ,field)
#define PRINT_ATTR_X64(field) __PRINT_ATTR("%#"PRIx64, (uint64_t), field)
#define PRINT_ATTR2(field1, field2) \
fprintf(fp, " %-28s %u %-28s %u\n", \
#field1, attr->field1, #field2, attr->field2)
Thanks,
