 476  *           MODULE_GetBinaryType
 477  *
 478  * The GetBinaryType function determines whether a file is executable
 479  * or not and if it is it returns what type of executable it is.
 480  * The type of executable is a property that determines in which
 481  * subsystem an executable file runs under.
 482  *
 483  * Binary types returned:
 484  * SCS_32BIT_BINARY: A Win32 based application
 485  * SCS_DOS_BINARY: An MS-Dos based application
 486  * SCS_WOW_BINARY: A Win16 based application
 487  * SCS_PIF_BINARY: A PIF file that executes an MS-Dos based app
 488  * SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
 489  * SCS_OS216_BINARY: A 16bit OS/2 based application
 490  *
 491  * Returns TRUE if the file is an executable in which case
 492  * the value pointed by lpBinaryType is set.
 493  * Returns FALSE if the file is not an executable or if the function fails.
 494  *
 495  * To do so it opens the file and reads in the header information
 496  * if the extended header information is not present it will
 497  * assume that the file is a DOS executable.
 498  * If the extended header information is present it will
 499  * determine if the file is a 16 or 32 bit Windows executable
 500  * by check the flags in the header.
 501  *
 502  * Note that .COM and .PIF files are only recognized by their
 503  * file name extension; but Windows does it the same way ...
