30 Targets
31
32DESCRIPTION
33 Each port of BFD to a different machine requries the creation
34 of a target back end. All the back end provides to the root
35 part of BFD is a structure containing pointers to functions
36 which perform certain low level operations on files. BFD
37 translates the applications's requests through a pointer into
5bff4f56 38 calls to the back end routines.
252b5132
RH
39
40 When a file is opened with <<bfd_openr>>, its format and
41 target are unknown. BFD uses various mechanisms to determine
42 how to interpret the file. The operations performed are:
43
44 o Create a BFD by calling the internal routine
45 <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
5bff4f56 46 target string supplied to <<bfd_openr>> and the new BFD pointer.
252b5132
RH
47
48 o If a null target string was provided to <<bfd_find_target>>,
49 look up the environment variable <<GNUTARGET>> and use
5bff4f56 50 that as the target string.
252b5132
RH
51
52 o If the target string is still <<NULL>>, or the target string is
53 <<default>>, then use the first item in the target vector
54 as the target type, and set <<target_defaulted>> in the BFD to
55 cause <<bfd_check_format>> to loop through all the targets.
56 @xref{bfd_target}. @xref{Formats}.
57
58 o Otherwise, inspect the elements in the target vector
59 one by one, until a match on target name is found. When found,
5bff4f56 60 use it.
252b5132
RH
61
62 o Otherwise return the error <<bfd_error_invalid_target>> to
63 <<bfd_openr>>.
64
65 o <<bfd_openr>> attempts to open the file using
66 <<bfd_open_file>>, and returns the BFD.
67
68 Once the BFD has been opened and the target selected, the file
69 format may be determined. This is done by calling
5bff4f56 70 <<bfd_check_format>> on the BFD with a suggested format.
252b5132
RH
71 If <<target_defaulted>> has been set, each possible target
72 type is tried to see if it recognizes the specified format.
73 <<bfd_check_format>> returns <<true>> when the caller guesses right.

87DESCRIPTION
88 This structure contains everything that BFD knows about a
89 target. It includes things like its byte order, name, and which
5bff4f56 90 routines to call to do various operations.
252b5132
RH
91
92 Every BFD points to a target structure with its <<xvec>>
5bff4f56 93 member.
252b5132
RH
94
95 The macros below are used to dispatch to functions through the
96 <<bfd_target>> vector. They are used in a number of macros further
97 down in @file{bfd.h}, and are also used when calling various
98 routines by hand inside the BFD implementation. The @var{arglist}
99 argument must be parenthesized; it contains all the arguments
5bff4f56 100 to the called function.
252b5132
RH
101
102 They make the documentation (more) unpleasant to read, so if
103 someone wants to fix this and not break the above, please do.

129 This is the structure which defines the type of BFD this is. The
130 <<xvec>> member of the struct <<bfd>> itself points here. Each
131 module that implements access to a different target under BFD,
132 defines one of these.
133
252b5132
RH
134 FIXME, these names should be rationalised with the names of
135 the entry points which call them. Too bad we can't have one
5bff4f56 136 macro to define them both!

1135 one in the environment variable <<GNUTARGET>>; if that is null or not
1136 defined, then choose the first entry in the target list.
1137 Passing in the string "default" or setting the environment
1138 variable to "default" will cause the first entry in the target
1139 list to be returned, and "target_defaulted" will be set in the
1140 BFD. This causes <<bfd_check_format>> to loop over all the
5bff4f56 1141 targets to find the one that matches the file being read.
