  24    This program allows you to build the files necessary to create
  25    DLLs to run on a system which understands PE format image files.
  26    (eg, Windows NT)
  27
  28    A DLL contains an export table which contains the information
  29    which the runtime loader needs to tie up references from a
  30    referencing program.
  31
  32    The export table is generated by this program by reading
  33    in a .DEF file or scanning the .a and .o files which will be in the
  34    DLL.  A .o file can contain information in special  ".drectve" sections
  35    with export information.
  36
  37    A DEF file contains any number of the following commands:
  38
  39
  40    NAME <name> [ , <base> ]
  41    The result is going to be <name>.EXE
  42
  43    LIBRARY <name> [ , <base> ]
  44    The result is going to be <name>.DLL
  45
  46    EXPORTS  ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] ) *
  47    Declares name1 as an exported symbol from the
  48    DLL, with optional ordinal number <integer>
  49
  50    IMPORTS  ( [ <name> = ] <name> . <name> ) *
  51    Ignored for compatibility
  52
  53    DESCRIPTION <string>
  54    Puts <string> into output .exp file in the .rdata section
  55
  56    [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
  57    Generates --stack|--heap <number-reserve>,<number-commit>
  58    in the output .drectve section.  The linker will
  59    see this and act upon it.
  60
  61    [CODE|DATA] <attr>+
  62    SECTIONS ( <sectionname> <attr>+ )*
  63    <attr> = READ | WRITE | EXECUTE | SHARED
  64    Generates --attr <sectionname> <attr> in the output
  65    .drectve section.  The linker will see this and act
  66    upon it.
  67
  68
  69    A -export:<name> in a .drectve section in an input .o or .a
  70    file to this program is equivalent to a EXPORTS <name>
  71    in a .DEF file.
  72
  73
  74
  75    The program generates output files with the prefix supplied
  76    on the command line, or in the def file, or taken from the first
  77    supplied argument.
  78
  79    The .exp.s file contains the information necessary to export
  80    the routines in the DLL.  The .lib.s file contains the information
  81    necessary to use the DLL's routines from a referencing program.
  82
  83
  84
  85    Example:
  86
  87    file1.c:
  88    asm (".section .drectve");
  89    asm (".ascii \"-export:adef\"");
  90
  91    adef(char *s)
  92    {
  93    printf("hello from the dll %s\n",s);
  94    }
  95
  96    bdef(char *s)
  97    {
  98    printf("hello from the dll and the other entry point %s\n",s);
  99    }
 100
 101    file2.c:
 102    asm (".section .drectve");
 103    asm (".ascii \"-export:cdef\"");
 104    asm (".ascii \"-export:ddef\"");
 105    cdef(char *s)
 106    {
 107    printf("hello from the dll %s\n",s);
 108    }
 109
 110    ddef(char *s)
 111    {
 112    printf("hello from the dll and the other entry point %s\n",s);
 113    }
 114
 115    printf()
 116    {
 117    return 9;
