From 70e009144e6781fe959c58dbea9e3803ca25cbe4 Mon Sep 17 00:00:00 2001
From: Ken Raeburn <raeburn@cygnus>
Date: Tue, 6 Jul 1993 20:20:31 +0000
Subject: Stricter prototyping, to force type conversions between 64-bit target
 and 32-bit host values.

* libbfd.c (bfd_xmalloc_by_size_t): New function.
* opncls.c (bfd_cache_init, bfd_open_file): Add prototypes to declarations.
(obstack_chunk_alloc): Use bfd_xmalloc_by_size_t.
(new_bfd): Prototype-style definition, using DEFUN.
(bfd_alloc_grow, bfd_alloc, bfd_zalloc, bfd_realloc): Size argument is type
size_t, not bfd_size_type.
* ieee.c (obstack_chunk_alloc): Use bfd_xmalloc_by_size_t.
* bfd.c (bfd_default_error_trap, bfd_error_trap,
bfd_error_nonrepresentabltrap): Prototypes.
* libbfd-in.h (bfd_alloc, bfd_zalloc, bfd_realloc, bfd_alloc_grow): Adjusted
prototypes for arg type change.
* archive.c (get_elt_at_filepos, do_slurp_bsd_armap, normalize,
do_slurp_coff_armap, bfd_construct_extended_name_table): Prototypes.

 DESCRIPTION
          bfd_fdopenr is to bfd_fopenr much like  fdopen is to fopen.
 	 It opens a BFD on a file already described by the @var{fd}

+	 supplied.
+
+	 When the file is later bfd_closed, the file descriptor will be closed.
+
+	 If the caller desires that this file descriptor be cached by BFD
+	 (opened as needed, closed as needed to free descriptors for
+	 other opens), with the supplied @var{fd} used as an initial
+	 file descriptor (but subject to closure at any time), set
+	 bfd->cacheable nonzero in the returned BFD.  The default is to
+	 assume no cacheing; the file descriptor will remain open until
+	 bfd_close, and will not be affected by BFD operations on other
+	 files.
 
          Possible errors are no_memory, invalid_target and system_call
