  22    This program allows you to build the files necessary to create
  23    DLLs to run on a system which understands PE format image files.
  24    (eg, Windows NT)
  25
  26    See "Peering Inside the PE: A Tour of the Win32 Portable Executable
  27    File Format", MSJ 1994, Volume 9 for more information.
  28    Also see "Microsoft Portable Executable and Common Object File Format,
  29    Specification 4.1" for more information.
  30
  31    A DLL contains an export table which contains the information
  32    which the runtime loader needs to tie up references from a
  33    referencing program.
  34
  35    The export table is generated by this program by reading
  36    in a .DEF file or scanning the .a and .o files which will be in the
  37    DLL.  A .o file can contain information in special  ".drectve" sections
  38    with export information.
  39
  40    A DEF file contains any number of the following commands:
  41
  42
  43    NAME <name> [ , <base> ]
  44    The result is going to be <name>.EXE
  45
  46    LIBRARY <name> [ , <base> ]
  47    The result is going to be <name>.DLL
  48
  49    EXPORTS  ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] ) *
  50    Declares name1 as an exported symbol from the
  51    DLL, with optional ordinal number <integer>
  52
  53    IMPORTS  ( [ <name> = ] <name> . <name> ) *
  54    Ignored for compatibility
  55
  56    DESCRIPTION <string>
  57    Puts <string> into output .exp file in the .rdata section
  58
  59    [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
  60    Generates --stack|--heap <number-reserve>,<number-commit>
  61    in the output .drectve section.  The linker will
  62    see this and act upon it.
  63
  64    [CODE|DATA] <attr>+
  65    SECTIONS ( <sectionname> <attr>+ )*
  66    <attr> = READ | WRITE | EXECUTE | SHARED
  67    Generates --attr <sectionname> <attr> in the output
  68    .drectve section.  The linker will see this and act
  69    upon it.
  70
  71
  72    A -export:<name> in a .drectve section in an input .o or .a
  73    file to this program is equivalent to a EXPORTS <name>
  74    in a .DEF file.
  75
  76
  77
  78    The program generates output files with the prefix supplied
  79    on the command line, or in the def file, or taken from the first
  80    supplied argument.
  81
  82    The .exp.s file contains the information necessary to export
  83    the routines in the DLL.  The .lib.s file contains the information
  84    necessary to use the DLL's routines from a referencing program.
  85

  96    printf("hello from the dll %s\n",s);

  98
  99    bdef(char *s)
 100    {
 101    printf("hello from the dll and the other entry point %s\n",s);
 102    }
 103
 104    file2.c:
 105    asm (".section .drectve");
 106    asm (".ascii \"-export:cdef\"");
 107    asm (".ascii \"-export:ddef\"");

 166 /* .idata section description
 167
 168    The .idata section is the import table.  It is a collection of several
 169    subsections used to keep the pieces for each dll together: .idata$[234567].
 170    IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
 171
 172    .idata$2 = Import Directory Table
 173    = array of IMAGE_IMPORT_DESCRIPTOR's.
 174
 175         DWORD   Characteristics;      - pointer to .idata$4
 176         DWORD   TimeDateStamp;        - currently always 0
 177         DWORD   ForwarderChain;       - currently always 0
 178         DWORD   Name;                 - pointer to dll's name
 179         PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
 180
 181    .idata$3 = null terminating entry for .idata$2.
 182
 183    .idata$4 = Import Lookup Table
 184    = array of array of pointers to hint name table.
 185    There is one for each dll being imported from, and each dll's set is
 186    terminated by a trailing NULL.
 187
 188    .idata$5 = Import Address Table
 189    = array of array of pointers to hint name table.
 190    There is one for each dll being imported from, and each dll's set is
 191    terminated by a trailing NULL.
 192    Initially, this table is identical to the Import Lookup Table.  However,
 193    at load time, the loader overwrites the entries with the address of the
 194    function.
 195
 196    .idata$6 = Hint Name Table
 197    = Array of { short, asciz } entries, one for each imported function.
 198    The `short' is the function's ordinal number.
 199
 200    .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc)
