A DEF file contains any number of the following commands:

+/* .idata section description
+
+ The .idata section is the import table. It is a collection of several
+ subsections used to keep the pieces for each dll together: .idata$[234567].
+ IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
+
+ .idata$2 = Import Directory Table
+ = array of IMAGE_IMPORT_DESCRIPTOR's.
+
+ DWORD Import Lookup Table; - pointer to .idata$4
+ DWORD TimeDateStamp; - currently always 0
+ DWORD ForwarderChain; - currently always 0
+ DWORD Name; - pointer to dll's name
+ PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
+
+ .idata$3 = null terminating entry for .idata$2.
+
+ .idata$4 = Import Lookup Table
+ = array of array of pointers to hint name table.
+ There is one for each dll being imported from, and each dll's set is
+ terminated by a trailing NULL.
+
+ .idata$5 = Import Address Table
+ = array of array of pointers to hint name table.
+ There is one for each dll being imported from, and each dll's set is
+ terminated by a trailing NULL.
+ Initially, this table is identical to the Import Lookup Table. However,
+ at load time, the loader overwrites the entries with the address of the
+ function.
+
+ .idata$6 = Hint Name Table
+ = Array of { short, asciz } entries, one for each imported function.
+ The `short' is the function's ordinal number.
+

+ <func_name_in_app> = <dll_name>.<func_name_in_dll>
+ <func_name_in_app> = <dll_name>.<number>
+ <dll_name>.<func_name_in_dll>
+ <dll_name>.<number>
+ Furthermore, the dll's name may or may not end with ".dll", which
+ complicates the parsing a little. Normally the dll's name is
+ passed to def_import() in the "module" parameter, but when it ends
+ with ".dll" it gets passed in "module" sans ".dll" and that needs
+ to be reappended.
+
+ def_import gets five parameters:
+ APP_NAME - the name of the function in the application, if
+ present, or NULL if not present.
+ MODULE - the name of the dll, possibly sans extension (ie, '.dll').
+ DLLEXT - the extension of the dll, if present, NULL if not present.
+ ENTRY - the name of the function in the dll, if present, or NULL.
+ ORD_VAL - the numerical tag of the function in the dll, if present,
+ or NULL. Exactly one of <entry> or <ord_val> must be
+ present (i.e., not NULL). */
