- DESCRIPTION
- Each port of BFD to a different machine requries the creation
- of a target back end. All the back end provides to the root
- part of BFD is a structure containing pointers to functions
- which perform certain low level operations on files. BFD
- translates the applications's requests through a pointer into
- calls to the back end routines.
-
- When a file is opened with <<bfd_openr>>, its format and
- target are unknown. BFD uses various mechanisms to determine
- how to interpret the file. The operations performed are:
-
- o Create a BFD by calling the internal routine
- <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
- target string supplied to <<bfd_openr>> and the new BFD pointer.
-
- o If a null target string was provided to <<bfd_find_target>>,
- look up the environment variable <<GNUTARGET>> and use
- that as the target string.
-
- o If the target string is still <<NULL>>, or the target string is
- <<default>>, then use the first item in the target vector
- as the target type, and set <<target_defaulted>> in the BFD to
- cause <<bfd_check_format>> to loop through all the targets.
- @xref{bfd_target}. @xref{Formats}.
-
- o Otherwise, inspect the elements in the target vector
- one by one, until a match on target name is found. When found,
- use it.
-
- o Otherwise return the error <<bfd_error_invalid_target>> to
- <<bfd_openr>>.
-
- o <<bfd_openr>> attempts to open the file using
- <<bfd_open_file>>, and returns the BFD.
-
- Once the BFD has been opened and the target selected, the file
- format may be determined. This is done by calling
- <<bfd_check_format>> on the BFD with a suggested format.
- If <<target_defaulted>> has been set, each possible target
- type is tried to see if it recognizes the specified format.
- <<bfd_check_format>> returns <<true>> when the caller guesses right.

-
- DESCRIPTION
- This structure contains everything that BFD knows about a
- target. It includes things like its byte order, name, and which
- routines to call to do various operations.
-
- Every BFD points to a target structure with its <<xvec>>
- member.
-
- The macros below are used to dispatch to functions through the
- <<bfd_target>> vector. They are used in a number of macros further
- down in @file{bfd.h}, and are also used when calling various
- routines by hand inside the BFD implementation. The @var{arglist}
- argument must be parenthesized; it contains all the arguments
- to the called function.
-
- They make the documentation (more) unpleasant to read, so if
- someone wants to fix this and not break the above, please do.
-
- .#define BFD_SEND(bfd, message, arglist) \
- . ((*((bfd)->xvec->message)) arglist)
- .
- .#ifdef DEBUG_BFD_SEND
- .#undef BFD_SEND
- .#define BFD_SEND(bfd, message, arglist) \
- . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
- . ((*((bfd)->xvec->message)) arglist) : \
- . (bfd_assert (__FILE__,__LINE__), NULL))
- .#endif
-
- For operations which index on the BFD format:
-
- .#define BFD_SEND_FMT(bfd, message, arglist) \
- . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist)
- .
- .#ifdef DEBUG_BFD_SEND
- .#undef BFD_SEND_FMT
- .#define BFD_SEND_FMT(bfd, message, arglist) \
- . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
- . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist) : \
- . (bfd_assert (__FILE__,__LINE__), NULL))
- .#endif
-
- This is the structure which defines the type of BFD this is. The
- <<xvec>> member of the struct <<bfd>> itself points here. Each
- module that implements access to a different target under BFD,
- defines one of these.
-
-
- FIXME, these names should be rationalised with the names of
- the entry points which call them. Too bad we can't have one
- macro to define them both!

- FUNCTION

-
- DESCRIPTION
- Return a pointer to the transfer vector for the object target
- named @var{target_name}. If @var{target_name} is <<NULL>>, choose the
- one in the environment variable <<GNUTARGET>>; if that is null or not
- defined, then choose the first entry in the target list.
- Passing in the string "default" or setting the environment
- variable to "default" will cause the first entry in the target
- list to be returned, and "target_defaulted" will be set in the
- BFD. This causes <<bfd_check_format>> to loop over all the
- targets to find the one that matches the file being read.
