DESCRIPTION
- Open a BFD for read access on an existing stdio stream. When
- the BFD is passed to <<bfd_close>>, the stream will be closed.
+ Create and return a BFD backed by a read-only @var{stream}.
+ The @var{stream} is created using @var{open}, accessed using
+ @var{pread} and destroyed using @var{close}.
+
+ Calls <<bfd_find_target>>, so @var{target} is interpreted as by
+ that function.
+
+ Calls @var{open} (which can call <<bfd_zalloc>> and
+ <<bfd_get_filename>>) to obtain the read-only stream backing
+ the BFD. @var{open} either succeeds returning the
+ non-<<NULL>> @var{stream}, or fails returning <<NULL>>
+ (setting <<bfd_error>>).
+
+ Calls @var{pread} to request @var{nbytes} of data from
+ @var{stream} starting at @var{offset} (e.g., via a call to
+ <<bfd_read>>). @var{pread} either succeeds returning the
+ number of bytes read (which can be less than @var{nbytes} when
+ end-of-file), or fails returning -1 (setting <<bfd_error>>).
+
+ Calls @var{close} when the BFD is later closed using
+ <<bfd_close>>. @var{close} either succeeds returning 0, or
+ fails returning -1 (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>>.

- default path configured into libbfd at build time.
