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

95DESCRIPTION
96 This structure contains everything that BFD knows about a
97 target. It includes things like its byte order, name, and which
98 routines to call to do various operations.
99
100 Every BFD points to a target structure with its <<xvec>>
101 member.
102
103 The macros below are used to dispatch to functions through the
104 <<bfd_target>> vector. They are used in a number of macros further
105 down in @file{bfd.h}, and are also used when calling various
106 routines by hand inside the BFD implementation. The @var{arglist}
107 argument must be parenthesized; it contains all the arguments
108 to the called function.
109
110 They make the documentation (more) unpleasant to read, so if
111 someone wants to fix this and not break the above, please do.
112
113.#define BFD_SEND(bfd, message, arglist) \
114. ((*((bfd)->xvec->message)) arglist)
115.
116.#ifdef DEBUG_BFD_SEND
117.#undef BFD_SEND
118.#define BFD_SEND(bfd, message, arglist) \
119. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
120. ((*((bfd)->xvec->message)) arglist) : \
121. (bfd_assert (__FILE__,__LINE__), NULL))
122.#endif
123
124 For operations which index on the BFD format:
125
126.#define BFD_SEND_FMT(bfd, message, arglist) \
127. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
128.
129.#ifdef DEBUG_BFD_SEND
130.#undef BFD_SEND_FMT
131.#define BFD_SEND_FMT(bfd, message, arglist) \
132. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
133. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
134. (bfd_assert (__FILE__,__LINE__), NULL))
135.#endif
136.
137 This is the structure which defines the type of BFD this is. The
138 <<xvec>> member of the struct <<bfd>> itself points here. Each
139 module that implements access to a different target under BFD,
140 defines one of these.
141
142 FIXME, these names should be rationalised with the names of
143 the entry points which call them. Too bad we can't have one
144 macro to define them both!
