A DLL contains an export table which contains the information
which the runtime loader needs to tie up references from a
- referencing program.

The export table is generated by this program by reading
in a .DEF file or scanning the .a and .o files which will be in the
DLL. A .o file can contain information in special ".drectve" sections
- with export information.
+ with export information.
A DEF file contains any number of the following commands:
- NAME <name> [ , <base> ]
+ NAME <name> [ , <base> ]
The result is going to be <name>.EXE
- LIBRARY <name> [ , <base> ]
+ LIBRARY <name> [ , <base> ]
The result is going to be <name>.DLL
EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
Declares name1 as an exported symbol from the
DLL, with optional ordinal number <integer>
- IMPORTS ( [ <name> = ] <name> . <name> ) *
- Ignored for compatibility
+ IMPORTS ( ( <internal-name> = <module-name> . <integer> )
+ | ( [ <internal-name> = ] <module-name> . <external-name> )) *
+ Declares that <external-name> or the exported function whoes ordinal number

+ <internal-name> is specified then this is the name that the imported
+ function will be refered to in the body of the DLL.
DESCRIPTION <string>
