All the back end provides to the root 42 part of BFD is a structure containing pointers to functions 43 which perform certain low level operations on files. BFD 44 translates the applications's requests through a pointer into 45 calls to the back end routines. 46 47 When a file is opened with <<bfd_openr>>, its format and 48 target are unknown. BFD uses various mechanisms to determine 49 how to interpret the file. The operations performed are: 50 51 o Create a BFD by calling the internal routine 52 <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the 53 target string supplied to <<bfd_openr>> and the new BFD pointer. 54 55 o If a null target string was provided to <<bfd_find_target>>, 56 look up the environment variable <<GNUTARGET>> and use 57 that as the target string. 58 59 o If the target string is still <<NULL>>, or the target string is 60 <<default>>, then use the first item in the target vector 61 as the target type, and set <<target_defaulted>> in the BFD to 62 cause <<bfd_check_format>> to loop through all the targets. 63 @xref{bfd_target}. @xref{Formats}. 64 65 o Otherwise, inspect the elements in the target vector 66 one by one, until a match on target name is found. When found, 67 use it. 68 69 o Otherwise return the error <<bfd_error_invalid_target>> to 70 <<bfd_openr>>. 71 72 o <<bfd_openr>> attempts to open the file using 73 <<bfd_open_file>>, and returns the BFD. 74 75 Once the BFD has been opened and the target selected, the file 76 format may be determined. This is done by calling 77 <<bfd_check_format>> on the BFD with a suggested format. 78 If <<target_defaulted>> has been set, each possible target 79 type is tried to see if it recognizes the specified format. 80 <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. 81@menu 82@* bfd_target:: 83@end menu 84*/ 85 86/* 87 88INODE 89 bfd_target, , Targets, Targets 90DOCDD 91SUBSECTION 92 bfd_target 93 94DESCRIPTION 95 This structure contains everything that BFD knows about a 96 target. It includes things like its byte order, name, and which 97 routines to call to do various operations. 98 99 Every BFD points to a target structure with its <<xvec>> 100 member. 101 102 The macros below are used to dispatch to functions through the 103 <<bfd_target>> vector. They are used in a number of macros further 104 down in @file{bfd.h}, and are also used when calling various 105 routines by hand inside the BFD implementation. The @var{arglist} 106 argument must be parenthesized; it contains all the arguments 107 to the called function. 108 109 They make the documentation (more) unpleasant to read, so if 110 someone wants to fix this and not break the above, please do. 111 112.#define BFD_SEND(bfd, message, arglist) \ 113.

Each 138 module that implements access to a different target under BFD, 139 defines one of these. 140 141 FIXME, these names should be rationalised with the names of 142 the entry points which call them.
