| 24 | DLLs to run on a system which understands PE format image files. |
| 25 | (eg, Windows NT) |

| 27 | See "Peering Inside the PE: A Tour of the Win32 Portable Executable |

| 30 | Specification 4.1" for more information. |
| 31 | |
| 32 | A DLL contains an export table which contains the information |
| 33 | which the runtime loader needs to tie up references from a |
| 34 | referencing program. |
| 35 | |
| 36 | The export table is generated by this program by reading |
| 37 | in a .DEF file or scanning the .a and .o files which will be in the |
| 38 | DLL. A .o file can contain information in special ".drectve" sections |
| 39 | with export information. |
| 40 | |
| 41 | A DEF file contains any number of the following commands: |
| 42 | |
| 43 | |
| 44 | NAME <name> [ , <base> ] |
| 45 | The result is going to be <name>.EXE |
| 46 | |
| 47 | LIBRARY <name> [ , <base> ] |
| 48 | The result is going to be <name>.DLL |
| 49 | |
| 50 | EXPORTS ( ( ( <name1> [ = <name2> ] ) |
| 51 | | ( <name1> = <module-name> . <external-name>)) |
| 52 | [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] [PRIVATE] ) * |
| 53 | Declares name1 as an exported symbol from the |
| 54 | DLL, with optional ordinal number <integer>. |
| 55 | Or declares name1 as an alias (forward) of the function <external-name> |
| 56 | in the DLL <module-name>. |
| 57 | |
| 58 | IMPORTS ( ( <internal-name> = <module-name> . <integer> ) |
| 59 | | ( [ <internal-name> = ] <module-name> . <external-name> )) * |
| 60 | Declares that <external-name> or the exported function whose ordinal number |
| 61 | is <integer> is to be imported from the file <module-name>. If |
| 62 | <internal-name> is specified then this is the name that the imported |
| 63 | function will be refereed to in the body of the DLL. |
| 64 | |
| 65 | DESCRIPTION <string> |
| 66 | Puts <string> into output .exp file in the .rdata section |
| 67 | |
| 68 | [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ] |
| 69 | Generates --stack|--heap <number-reserve>,<number-commit> |
| 70 | in the output .drectve section. The linker will |
| 71 | see this and act upon it. |
| 72 | |
| 73 | [CODE|DATA] <attr>+ |
| 74 | SECTIONS ( <sectionname> <attr>+ )* |
| 75 | <attr> = READ | WRITE | EXECUTE | SHARED |
| 76 | Generates --attr <sectionname> <attr> in the output |
| 77 | .drectve section. The linker will see this and act |
| 78 | upon it. |
| 79 | |
| 80 | |
| 81 | A -export:<name> in a .drectve section in an input .o or .a |
| 82 | file to this program is equivalent to a EXPORTS <name> |
| 83 | in a .DEF file. |
| 84 | |
| 85 | |
| 86 | |
| 87 | The program generates output files with the prefix supplied |
| 88 | on the command line, or in the def file, or taken from the first |
| 89 | supplied argument. |
| 90 | |
| 91 | The .exp.s file contains the information necessary to export |
| 92 | the routines in the DLL. The .lib.s file contains the information |
| 93 | necessary to use the DLL's routines from a referencing program. |
| 94 | |

| 202 | subsections used to keep the pieces for each dll together: .idata$[234567]. |
| 203 | IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc. |
| 204 | |
| 205 | .idata$2 = Import Directory Table |
| 206 | = array of IMAGE_IMPORT_DESCRIPTOR's. |
| 207 | |
| 208 | DWORD Import Lookup Table; - pointer to .idata$4 |
| 209 | DWORD TimeDateStamp; - currently always 0 |
| 210 | DWORD ForwarderChain; - currently always 0 |
| 211 | DWORD Name; - pointer to dll's name |
| 212 | PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5 |
| 213 | |
| 214 | .idata$3 = null terminating entry for .idata$2. |
| 215 | |
| 216 | .idata$4 = Import Lookup Table |
| 217 | = array of array of pointers to hint name table. |

| 222 | = array of array of pointers to hint name table. |
| 223 | There is one for each dll being imported from, and each dll's set is |
| 224 | terminated by a trailing NULL. |
| 225 | Initially, this table is identical to the Import Lookup Table. However, |
| 226 | at load time, the loader overwrites the entries with the address of the |
| 227 | function. |
| 228 | |
| 229 | .idata$6 = Hint Name Table |

| 1103 | ENTRY - the name of the function in the dll, if present, or NULL. |
| 1104 | ORD_VAL - the numerical tag of the function in the dll, if present, |
