Why use an fd_str instead of passing an int64_t into the error
message? This also assumed sizeof(long) == 8, which isn't true on
32-bit hosts, so %ld should be %"PRId64".
Can I pass an int64_t into the message if it takes a string?
I thought int64_t was a long long in 32-bit mode, but perhaps that's not
always the case?
The PRId64 format specifier macro from the C standard hides this so
you can pass int64_t values to printf()-style functions in a portable
way.

Thanks, I'll use PRId64.
