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.
26 A DLL contains an export table which contains the information
27 which the runtime loader needs to tie up references from a
30 The export table is generated by this program by reading
31 in a .DEF file or scanning the .a and .o files which will be in the
32 DLL. A .o file can contain information in special ".drective" sections
33 with export information.
35 A DEF file contains any number of the following commands:
38 NAME <name> [ , <base> ]
39 The result is going to be <name>.EXE
41 LIBRARY <name> [ , <base> ]
42 The result is going to be <name>.DLL
44 EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] ) *
45 Declares name1 as an exported symbol from the
46 DLL, with optional ordinal number <integer>
48 IMPORTS ( [ <name> = ] <name> . <name> ) *
49 Ignored for compatibility
52 Puts <string> into output .exp file in the .rdata section
54 [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
55 Generates --stack|--heap <number-reserve>,<number-commit>
56 in the output .drective section. The linker will
57 see this and act upon it.
60 SECTIONS ( <sectionname> <attr>+ )*
61 <attr> = READ | WRITE | EXECUTE | SHARED
62 Generates --attr <sectionname> <attr> in the output
63 .drective section. The linker will see this and act
67 A -export:<name> in a .drective section in an input .o or .a
68 file to this program is equivalent to a EXPORTS <name>
73 The program generates output files with the prefix supplied
74 on the command line, or in the def file, or taken from the first
77 The .exp.s file contains the information necessary to export
78 the routines in the DLL. The .lib.s file contains the information
79 necessary to use the DLL's routines from a referencing program.
