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) \ +.
