40DESCRIPTION
7dee875e 41 Each port of BFD to a different machine requires the creation
252b5132
RH
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
5bff4f56 46 calls to the back end routines.
252b5132
RH
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
5bff4f56 54 target string supplied to <<bfd_openr>> and the new BFD pointer.
252b5132
RH
55
56 o If a null target string was provided to <<bfd_find_target>>,
57 look up the environment variable <<GNUTARGET>> and use
5bff4f56 58 that as the target string.
252b5132
RH
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,
5bff4f56 68 use it.
252b5132
RH
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
5bff4f56 78 <<bfd_check_format>> on the BFD with a suggested format.
252b5132
RH
79 If <<target_defaulted>> has been set, each possible target
80 type is tried to see if it recognizes the specified format.
b34976b6 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
5bff4f56 98 routines to call to do various operations.
252b5132
RH
99
100 Every BFD points to a target structure with its <<xvec>>
5bff4f56 101 member.
252b5132
RH
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
5bff4f56 108 to the called function.
252b5132
RH
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.

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
252b5132
RH
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
5bff4f56 144 macro to define them both!
