  41 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.

  95
  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
 114 .#define BFD_SEND(bfd, message, arglist) \
 115 .  ((*((bfd)->xvec->message)) arglist)
 116 .
 117 .#ifdef DEBUG_BFD_SEND
 118 .#undef BFD_SEND
 119 .#define BFD_SEND(bfd, message, arglist) \
 120 .  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
 121 .    ((*((bfd)->xvec->message)) arglist) : \
 122 .    (bfd_assert (__FILE__,__LINE__), NULL))
 123 .#endif
 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!
