30	Targets

32DESCRIPTION
33	Each port of BFD to a different machine requires the creation
34	of a target back end. All the back end provides to the root
35	part of BFD is a structure containing pointers to functions
36	which perform certain low level operations on files. BFD
37	translates the applications's requests through a pointer into
38	calls to the back end routines.
39
40	When a file is opened with <<bfd_openr>>, its format and
41	target are unknown. BFD uses various mechanisms to determine
42	how to interpret the file. The operations performed are:
43
44	o Create a BFD by calling the internal routine
45	<<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
46	target string supplied to <<bfd_openr>> and the new BFD pointer.
47
48	o If a null target string was provided to <<bfd_find_target>>,
49	look up the environment variable <<GNUTARGET>> and use
50	that as the target string.
51
52	o If the target string is still <<NULL>>, or the target string is
53	<<default>>, then use the first item in the target vector
54	as the target type, and set <<target_defaulted>> in the BFD to
55	cause <<bfd_check_format>> to loop through all the targets.
56	@xref{bfd_target}.  @xref{Formats}.
57
58	o Otherwise, inspect the elements in the target vector
59	one by one, until a match on target name is found. When found,
60	use it.
61
62	o Otherwise return the error <<bfd_error_invalid_target>> to
63	<<bfd_openr>>.
64
65	o <<bfd_openr>> attempts to open the file using
66	<<bfd_open_file>>, and returns the BFD.
67
68	Once the BFD has been opened and the target selected, the file
69	format may be determined. This is done by calling
70	<<bfd_check_format>> on the BFD with a suggested format.
71	If <<target_defaulted>> has been set, each possible target
72	type is tried to see if it recognizes the specified format.
73	<<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

87DESCRIPTION
88	This structure contains everything that BFD knows about a
89	target. It includes things like its byte order, name, and which
90	routines to call to do various operations.
91
92	Every BFD points to a target structure with its <<xvec>>
93	member.
94
95	The macros below are used to dispatch to functions through the
96	<<bfd_target>> vector. They are used in a number of macros further
97	down in @file{bfd.h}, and are also used when calling various
98	routines by hand inside the BFD implementation.  The @var{arglist}
99	argument must be parenthesized; it contains all the arguments
100	to the called function.
101
102	They make the documentation (more) unpleasant to read, so if
103	someone wants to fix this and not break the above, please do.
104
105.#define BFD_SEND(bfd, message, arglist) \
106.  ((*((bfd)->xvec->message)) arglist)
107.
108.#ifdef DEBUG_BFD_SEND
109.#undef BFD_SEND
110.#define BFD_SEND(bfd, message, arglist) \
111.  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
112.    ((*((bfd)->xvec->message)) arglist) : \
113.    (bfd_assert (__FILE__,__LINE__), NULL))
114.#endif
115
116	For operations which index on the BFD format:
117
118.#define BFD_SEND_FMT(bfd, message, arglist) \
119.  (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
120.
121.#ifdef DEBUG_BFD_SEND
122.#undef BFD_SEND_FMT
123.#define BFD_SEND_FMT(bfd, message, arglist) \
124.  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
125.   (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
126.   (bfd_assert (__FILE__,__LINE__), NULL))
127.#endif
128.
129	This is the structure which defines the type of BFD this is.  The
130	<<xvec>> member of the struct <<bfd>> itself points here.  Each
131	module that implements access to a different target under BFD,
132	defines one of these.
133
134	FIXME, these names should be rationalised with the names of
135	the entry points which call them. Too bad we can't have one
136	macro to define them both!

1364DESCRIPTION
1365	Return a pointer to the first transfer vector in the list of
1366	transfer vectors maintained by BFD that produces a non-zero
1367	result when passed to the function @var{search_func}.  The
1368	parameter @var{data} is passed, unexamined, to the search
1369	function.
