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

96DESCRIPTION
97 This structure contains everything that BFD knows about a
98 target. It includes things like its byte order, name, and which
99 routines to call to do various operations.
100
101 Every BFD points to a target structure with its <<xvec>>
102 member.
103
104 The macros below are used to dispatch to functions through the
105 <<bfd_target>> vector. They are used in a number of macros further
106 down in @file{bfd.h}, and are also used when calling various
107 routines by hand inside the BFD implementation. The @var{arglist}
108 argument must be parenthesized; it contains all the arguments
109 to the called function.
110
111 They make the documentation (more) unpleasant to read, so if
112 someone wants to fix this and not break the above, please do.
113
114.#define BFD_SEND(bfd, message, arglist) \
115. ((*((bfd)->xvec->message)) arglist)
116.
117.#ifdef DEBUG_BFD_SEND
118.#undef BFD_SEND
119.#define BFD_SEND(bfd, message, arglist) \
120. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
121. ((*((bfd)->xvec->message)) arglist) : \
122. (bfd_assert (__FILE__,__LINE__), NULL))
123.#endif
124
125 For operations which index on the BFD format:
126
127.#define BFD_SEND_FMT(bfd, message, arglist) \
128. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
129.
130.#ifdef DEBUG_BFD_SEND
131.#undef BFD_SEND_FMT
132.#define BFD_SEND_FMT(bfd, message, arglist) \
133. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
134. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
135. (bfd_assert (__FILE__,__LINE__), NULL))
136.#endif
137.
138 This is the structure which defines the type of BFD this is. The
139 <<xvec>> member of the struct <<bfd>> itself points here. Each
140 module that implements access to a different target under BFD,
141 defines one of these.
142
143 FIXME, these names should be rationalised with the names of
144 the entry points which call them. Too bad we can't have one
145 macro to define them both!
