DESCRIPTION

<<bfd_close>>. @var{close} either succeeds returning 0, or
fails returning -1 (setting <<bfd_error>>).
+ Calls @var{stat} to fill in a stat structure for bfd_stat,
+ bfd_get_size, and bfd_get_mtime calls. @var{stat} returns 0
+ on success, or returns -1 on failure (setting <<bfd_error>>).
+
If <<bfd_openr_iovec>> returns <<NULL>> then an error has
occurred. Possible errors are <<bfd_error_no_memory>>,
<<bfd_error_invalid_target>> and <<bfd_error_system_call>>.
