545 * Thus we need to use a special assembly glue routine
546 * (CallRegisterLongProc instead of CallRegisterShortProc).

551 * FIXME: The called function uses EBX to return the number of

594 * argument processing is done on both the 32-bit and the 16-bit side:
595 * The 32-bit side prepares arguments, copying them onto the stack.
597 * When this routine is called, the first word on the stack is the
598 * number of argument bytes prepared by the 32-bit code, and EDX
599 * contains the 16-bit target address.
601 * The called 16-bit routine is another relaycode, doing further
602 * argument processing and then calling the real 16-bit target
603 * whose address is stored at [bp-04].
605 * The call proceeds using a normal CallRegisterShortProc.
606 * After return from the 16-bit relaycode, the arguments need
607 * to be copied *back* to the 32-bit stack, since the 32-bit
608 * relaycode processes output parameters.
610 * Note that we copy twice the number of arguments, since some of the
611 * 16-bit relaycodes in SYSTHUNK.DLL directly access the original
612 * arguments of the caller!
614 * (Note that this function seems only to be used for

1162 * GetBinaryType32A [KERNEL32.280]
1164 * The GetBinaryType function determines whether a file is executable
1165 * or not and if it is it returns what type of executable it is.
1166 * The type of executable is a property that determines in which
1167 * subsystem an executable file runs under.
1169 * lpApplicationName: points to a fully qualified path of the file to test
1170 * lpBinaryType: points to a variable that will receive the binary type info
1172 * Binary types returned:
1173 * SCS_32BIT_BINARY: A win32 based application
1174 * SCS_DOS_BINARY: An MS-Dos based application
1175 * SCS_WOW_BINARY: A 16bit OS/2 based application
1176 * SCS_PIF_BINARY: A PIF file that executes an MS-Dos based app ( Not implemented )
1177 * SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
1178 * SCS_OS216_BINARY: A 16bit Windows based application ( Not implemented )
1180 * Returns TRUE if the file is an executable in which case
1181 * the value pointed by lpBinaryType is set.
1182 * Returns FALSE if the file is not an executable or if the function fails.
1184 * This function is not complete. It can only determine if a file
1185 * is a DOS, 32bit/16bit Windows executable. Also .COM file support
1187 * To do so it opens the file and reads in the header information
1188 * if the extended header information is not presend it will
1189 * assume that that the file is a DOS executable.
1190 * If the extended header information is present it will
1191 * determine if the file is an 16 or 32 bit Windows executable
1192 * by check the flags in the header.
