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. -@menu -@* bfd_target:: -@end menu -*/ - - -/* - -INODE - bfd_target, , Targets, Targets -DOCDD -SUBSECTION - bfd_target - -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) \ -.
