DESCRIPTION
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.

96
DESCRIPTION
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

123

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!

SYNOPSIS
1463
        const bfd_target *bfd_search_for_target

DESCRIPTION
1468
        Return a pointer to the first transfer vector in the list of
1469
        transfer vectors maintained by BFD that produces a non-zero
1470
        result when passed to the function @var{search_func}.  The
1471
        parameter @var{data} is passed, unexamined, to the search
1472
        function.
