POSIX atom terms to describe transaction errors.

The following definitions are from RFC 1350 Appendix I (p. 9)

atom        value     meaning

:error      0         Not defined, see error message (if any).
:enoent     1         File not found.
:eacces     2         Access violation.
-           3         Disk full or allocation exceeded.
:enotsup    4         Illegal TFTP operation.
:eninval    5         Unknown transfer ID.
-           6         File already exists.
:enouser    7         No such user.
