41DESCRIPTION
7dee875e 42 Each port of BFD to a different machine requires the creation
252b5132
RH
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
5bff4f56 47 calls to the back end routines.
252b5132
RH
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
5bff4f56 55 target string supplied to <<bfd_openr>> and the new BFD pointer.
252b5132
RH
56
57 o If a null target string was provided to <<bfd_find_target>>,
58 look up the environment variable <<GNUTARGET>> and use
5bff4f56 59 that as the target string.
252b5132
RH
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,
5bff4f56 69 use it.
252b5132
RH
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
5bff4f56 79 <<bfd_check_format>> on the BFD with a suggested format.
252b5132
RH
80 If <<target_defaulted>> has been set, each possible target
81 type is tried to see if it recognizes the specified format.
b34976b6 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
5bff4f56 99 routines to call to do various operations.
252b5132
RH
100
101 Every BFD points to a target structure with its <<xvec>>
5bff4f56 102 member.
252b5132
RH
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
5bff4f56 109 to the called function.
252b5132
RH
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.

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
252b5132
RH
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
5bff4f56 145 macro to define them both!

1477DESCRIPTION
1478 Return a pointer to the transfer vector for the object target
1479 named @var{target_name}. If @var{target_name} is <<NULL>>,
1480 choose the one in the environment variable <<GNUTARGET>>; if
1481 that is null or not defined, then choose the first entry in the
1482 target list. Passing in the string "default" or setting the
1483 environment variable to "default" will cause the first entry in
1484 the target list to be returned, and "target_defaulted" will be
1485 set in the BFD if @var{abfd} isn't <<NULL>>. This causes
1486 <<bfd_check_format>> to loop over all the targets to find the
1487 one that matches the file being read.
1488 If @var{is_bigendian} is not <<NULL>>, then set this value to target's
1489 endian mode. True for big-endian, FALSE for little-endian or for
1490 invalid target.
1491 If @var{underscoring} is not <<NULL>>, then set this value to target's
1492 underscoring mode. Zero for none-underscoring, -1 for invalid target,
1493 else the value of target vector's symbol underscoring.
1494 If @var{def_target_arch} is not <<NULL>>, then set it to the architecture
1495 string specified by the target_name.
