All the back end provides to the root 35 part of BFD is a structure containing pointers to functions 36 which perform certain low level operations on files. BFD 37 translates the applications's requests through a pointer into 38 calls to the back end routines. 39 40 When a file is opened with <<bfd_openr>>, its format and 41 target are unknown. BFD uses various mechanisms to determine 42 how to interpret the file. The operations performed are: 43 44 o Create a BFD by calling the internal routine 45 <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the 46 target string supplied to <<bfd_openr>> and the new BFD pointer. 47 48 o If a null target string was provided to <<bfd_find_target>>, 49 look up the environment variable <<GNUTARGET>> and use 50 that as the target string. 51 52 o If the target string is still <<NULL>>, or the target string is 53 <<default>>, then use the first item in the target vector 54 as the target type, and set <<target_defaulted>> in the BFD to 55 cause <<bfd_check_format>> to loop through all the targets. 56 @xref{bfd_target}. @xref{Formats}. 57 58 o Otherwise, inspect the elements in the target vector 59 one by one, until a match on target name is found. When found, 60 use it. 61 62 o Otherwise return the error <<bfd_error_invalid_target>> to 63 <<bfd_openr>>. 64 65 o <<bfd_openr>> attempts to open the file using 66 <<bfd_open_file>>, and returns the BFD. 67 68 Once the BFD has been opened and the target selected, the file 69 format may be determined. This is done by calling 70 <<bfd_check_format>> on the BFD with a suggested format. 71 If <<target_defaulted>> has been set, each possible target 72 type is tried to see if it recognizes the specified format. 73 <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. 74@menu 75@* bfd_target:: 76@end menu 77*/ 78 79/* 80 81INODE 82 bfd_target, , Targets, Targets 83DOCDD 84SUBSECTION 85 bfd_target 86 87DESCRIPTION 88 This structure contains everything that BFD knows about a 89 target. It includes things like its byte order, name, and which 90 routines to call to do various operations. 91 92 Every BFD points to a target structure with its <<xvec>> 93 member. 94 95 The macros below are used to dispatch to functions through the 96 <<bfd_target>> vector. They are used in a number of macros further 97 down in @file{bfd.h}, and are also used when calling various 98 routines by hand inside the BFD implementation. The @var{arglist} 99 argument must be parenthesized; it contains all the arguments 100 to the called function. 101 102 They make the documentation (more) unpleasant to read, so if 103 someone wants to fix this and not break the above, please do. 104 105.#define BFD_SEND(bfd, message, arglist) \ 106.

Each 131 module that implements access to a different target under BFD, 132 defines one of these. 133 134 FIXME, these names should be rationalised with the names of 135 the entry points which call them.
