All the back end provides to the root 43 part of BFD is a structure containing pointers to functions 44 which perform certain low level operations on files. BFD 45 translates the applications's requests through a pointer into 46 calls to the back end routines. 47 48 When a file is opened with <<bfd_openr>>, its format and 49 target are unknown. BFD uses various mechanisms to determine 50 how to interpret the file. The operations performed are: 51 52 o Create a BFD by calling the internal routine 53 <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the 54 target string supplied to <<bfd_openr>> and the new BFD pointer. 55 56 o If a null target string was provided to <<bfd_find_target>>, 57 look up the environment variable <<GNUTARGET>> and use 58 that as the target string. 59 60 o If the target string is still <<NULL>>, or the target string is 61 <<default>>, then use the first item in the target vector 62 as the target type, and set <<target_defaulted>> in the BFD to 63 cause <<bfd_check_format>> to loop through all the targets. 64 @xref{bfd_target}. @xref{Formats}. 65 66 o Otherwise, inspect the elements in the target vector 67 one by one, until a match on target name is found. When found, 68 use it. 69 70 o Otherwise return the error <<bfd_error_invalid_target>> to 71 <<bfd_openr>>. 72 73 o <<bfd_openr>> attempts to open the file using 74 <<bfd_open_file>>, and returns the BFD. 75 76 Once the BFD has been opened and the target selected, the file 77 format may be determined. This is done by calling 78 <<bfd_check_format>> on the BFD with a suggested format. 79 If <<target_defaulted>> has been set, each possible target 80 type is tried to see if it recognizes the specified format. 81 <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. 82@menu 83@* bfd_target:: 84@end menu 85*/ 86 87/* 88 89INODE 90 bfd_target, , Targets, Targets 91DOCDD 92SUBSECTION 93 bfd_target 94 95DESCRIPTION 96 This structure contains everything that BFD knows about a 97 target. It includes things like its byte order, name, and which 98 routines to call to do various operations. 99 100 Every BFD points to a target structure with its <<xvec>> 101 member. 102 103 The macros below are used to dispatch to functions through the 104 <<bfd_target>> vector. They are used in a number of macros further 105 down in @file{bfd.h}, and are also used when calling various 106 routines by hand inside the BFD implementation. The @var{arglist} 107 argument must be parenthesized; it contains all the arguments 108 to the called function. 109 110 They make the documentation (more) unpleasant to read, so if 111 someone wants to fix this and not break the above, please do. 112 113.#define BFD_SEND(bfd, message, arglist) \ 114.

Each 139 module that implements access to a different target under BFD, 140 defines one of these. 141 142 FIXME, these names should be rationalised with the names of 143 the entry points which call them.
