The linker (and other tools on vms) depend on that. Unix doesn't know about 'formatted' files, so reading and writing such an object file in a unix environment is not trivial. With the tool 'file' (available on all vms ftp sites), one can view and change the attributes of a file. Changing from 'variable length' to 'fixed length, 512 bytes' reveals the record length at the first 2 bytes of every record. The same happens during the transfer of object files from vms to unix, at least with ucx, dec's implementation of tcp/ip. The vms format repeats the length at bytes 2 & 3 of every record. On the first call (file_format == FF_UNKNOWN) we check if the first and the third byte pair (!) of the record match. If they do it's an object file in an unix environment or with wrong attributes (FF_FOREIGN), else we should be in a vms environment where read() returns the record size (FF_NATIVE). reading is always done in 2 steps. first just the record header is read and the length extracted by get_header_values then the read buffer is adjusted and the remaining bytes are read in. all file i/o is always done on even file positions */ int _bfd_vms_get_record (abfd) bfd *abfd; { int test_len, test_start, remaining; unsigned char *vms_buf; #if VMS_DEBUG vms_debug (8, "_bfd_vms_get_record\n"); #endif /* minimum is 6 bytes on Alpha (2 bytes length, 2 bytes record id, 2 bytes length repeated) on VAX there's no length information in the record so start with OBJ_S_C_MAXRECSIZ */ if (PRIV (buf_size) == 0) { bfd_size_type amt; if (PRIV (is_vax)) { amt = OBJ_S_C_MAXRECSIZ; PRIV (file_format) = FF_VAX; } else amt = 6; PRIV (vms_buf) = (unsigned char *) bfd_malloc (amt); PRIV (buf_size) = amt; } vms_buf = PRIV (vms_buf); if (vms_buf == 0) return -1; switch (PRIV (file_format)) { case FF_UNKNOWN: case FF_FOREIGN: test_len = 6; /* probe 6 bytes */ test_start = 2; /* where the record starts */ break; case FF_NATIVE: test_len = 4; test_start = 0; break; default: case FF_VAX: test_len = 0; test_start = 0; break; } /* skip odd alignment byte */ if (bfd_tell (abfd) & 1) { if (bfd_bread (PRIV (vms_buf), (bfd_size_type) 1, abfd) != 1) { bfd_set_error (bfd_error_file_truncated); return 0; } } /* read the record header on Alpha. */ if ((test_len != 0) && (bfd_bread (PRIV (vms_buf), (bfd_size_type) test_len, abfd) != (bfd_size_type) test_len)) { bfd_set_error (bfd_error_file_truncated); return 0; } /* check file format on first call */ if (PRIV (file_format) == FF_UNKNOWN) { /* record length repeats ?
