If inbuf is non-NULL, the memory pointed to by inbuf is - * used as the input file contents. Otherwise, the contents are loaded from - * the file at path file_name. Even if inbuf is non-NULL, a file_name - * parameter should be specified for error reporting. Similarly, if outbuf is - * non-NULL, upon return, outbuf will point to a buffer containing the - * unprebound binary and outlen will point to the length of the output buffer. - * This buffer is vm_allocate'd and therefore should be vm_deallocate'd when it - * is no longer needed. If outbuf is NULL, and output_file is not NULL the - * update file is written to output_file, if outbuf is NULL and output_file is - * NULL, it is written to file_name. - * If unprebind() is successful it returns REDO_PREBINDING_SUCCESS otherwise it - * returns REDO_PREBINDING_FAILURE If the binary is already unprebound (i.e. it - * has the MH_PREBINDABLE flag set) then REDO_PREBINDING_NOT_NEEDED is returned. - * If the binary is not prebound and not prebindable, - * REDO_PREBINDING_NOT_PREBOUND is returned. If zero_checksum is non-zero then - * the cksum field the LC_PREBIND_CKSUM load command (if any) is set to zero on - * output, otherwise it is left alone. - * Unprebinding slides dynamic libraries to address zero, resets prebound - * symbols to address zero and type undefined, resets symbol pointers, removes - * LC_PREBOUND_DYLIB commands, resets library timestamps, resets two-level hints - * and updates relocation entries if necessary. Unprebound binaries have - * the MH_PREBINDABLE flag set, but not MH_PREBOUND. It will also set the the - * MH_ALLMODSBOUND flag if all two-level libraries were used and all modules - * were found to be bound in the LC_PREBOUND_DYLIB commands. - * As unprebinding is intended to produce a canonical Mach-O - * binary, bundles and non-prebound executables and dylibs are acceptable - * as input. For these files, the unprebind operation will zero library - * time stamps and version numbers and zero entries in the two-level hints - * table. These files will not gain the MH_PREBINDABLE flag. - * All resulting binaries successfully processed by unprebind() will have - * the MH_CANONICAL flag. - */ -extern -enum redo_prebinding_retval -unprebind( -const char *file_name, -const char *output_file, -const char *program_name, -char **error_message, -int zero_checksum, -void *inbuf, -unsigned long inlen, -void **outbuf, -unsigned long *outlen); - -enum object_file_type_retval { - OFT_OTHER, - OFT_EXECUTABLE, - OFT_DYLIB, - OFT_BUNDLE, - OFT_ARCHIVE, - OFT_INCONSISTENT, - OFT_FILE_ERROR -}; - -/* - * object_file_type() takes a file_name and determines what type of object - * file it is.
