DESCRIPTION
40
	Each port of BFD to a different machine requires the creation
41
	of a target back end. All the back end provides to the root
42
	part of BFD is a structure containing pointers to functions
43
	which perform certain low level operations on files. BFD
44
	translates the applications's requests through a pointer into
45
	calls to the back end routines.
46
 
47
	When a file is opened with <>, its format and
48
	target are unknown. BFD uses various mechanisms to determine
49
	how to interpret the file. The operations performed are:
50
 
51
	o Create a BFD by calling the internal routine
52
	<<_bfd_new_bfd>>, then call <> with the
53
	target string supplied to <> and the new BFD pointer.
54
 
55
	o If a null target string was provided to <>,
56
	look up the environment variable <> and use
57
	that as the target string.
58
 
59
	o If the target string is still <>, or the target string is
60
	<>, then use the first item in the target vector
61
	as the target type, and set <> in the BFD to
62
	cause <> to loop through all the targets.
63
	@xref{bfd_target}.  @xref{Formats}.
64
 
65
	o Otherwise, inspect the elements in the target vector
66
	one by one, until a match on target name is found. When found,
67
	use it.
68
 
69
	o Otherwise return the error <> to
70
	<>.
71
 
72
	o <> attempts to open the file using
73
	<>, and returns the BFD.
74
 
75
	Once the BFD has been opened and the target selected, the file
76
	format may be determined. This is done by calling
77
	<> on the BFD with a suggested format.
78
	If <> has been set, each possible target
79
	type is tried to see if it recognizes the specified format.
80
	<> returns <> when the caller guesses right.

DESCRIPTION
95
	This structure contains everything that BFD knows about a
96
	target. It includes things like its byte order, name, and which
97
	routines to call to do various operations.
98
 
99
	Every BFD points to a target structure with its <>
100
	member.
101
 
102
	The macros below are used to dispatch to functions through the
103
	<> vector. They are used in a number of macros further
104
	down in @file{bfd.h}, and are also used when calling various
105
	routines by hand inside the BFD implementation.  The @var{arglist}
106
	argument must be parenthesized; it contains all the arguments
107
	to the called function.
108
 
109
	They make the documentation (more) unpleasant to read, so if
110
	someone wants to fix this and not break the above, please do.

	For operations which index on the BFD format:
124
 
125
.#define BFD_SEND_FMT(bfd, message, arglist) \
126
.  (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
127

128
.#ifdef DEBUG_BFD_SEND
129
.#undef BFD_SEND_FMT
130
.#define BFD_SEND_FMT(bfd, message, arglist) \
131
.  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
132
.   (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
133
.   (bfd_assert (__FILE__,__LINE__), NULL))
134
.#endif
135
.
136
	This is the structure which defines the type of BFD this is.  The
137
	<> member of the struct <> itself points here.  Each
138
	module that implements access to a different target under BFD,
139
	defines one of these.
140
 
141
	FIXME, these names should be rationalised with the names of
142
	the entry points which call them. Too bad we can't have one
143
	macro to define them both!

SYNOPSIS

					       const char **def_target_arch);
1587
DESCRIPTION
1588
        Return a pointer to the transfer vector for the object target
1589
        named @var{target_name}.  If @var{target_name} is <>,
1590
        choose the one in the environment variable <>; if
1591
        that is null or not defined, then choose the first entry in the
1592
        target list.  Passing in the string "default" or setting the
1593
        environment variable to "default" will cause the first entry in
1594
        the target list to be returned, and "target_defaulted" will be
1595
        set in the BFD if @var{abfd} isn't <>.  This causes
1596
        <> to loop over all the targets to find the
1597
        one that matches the file being read.
1598
	If @var{is_bigendian} is not <>, then set this value to target's
1599
	endian mode. True for big-endian, FALSE for little-endian or for
1600
	invalid target.
1601
	If @var{underscoring} is not <>, then set this value to target's
1602
	underscoring mode. Zero for none-underscoring, -1 for invalid target,
1603
	else the value of target vector's symbol underscoring.
1604
	If @var{def_target_arch} is not <>, then set it to the architecture
1605
	string specified by the target_name.
