 504  * The GetBinaryType function determines whether a file is executable
 505  * or not and if it is it returns what type of executable it is.
 506  * The type of executable is a property that determines in which
 507  * subsystem an executable file runs under.
 508  *
 509  * Binary types returned:
 510  * SCS_32BIT_BINARY: A Win32 based application
 511  * SCS_DOS_BINARY: An MS-Dos based application
 512  * SCS_WOW_BINARY: A Win16 based application
 513  * SCS_PIF_BINARY: A PIF file that executes an MS-Dos based app
 514  * SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
 515  * SCS_OS216_BINARY: A 16bit OS/2 based application
 516  *
 517  * Returns TRUE if the file is an executable in which case
 518  * the value pointed by lpBinaryType is set.
 519  * Returns FALSE if the file is not an executable or if the function fails.
 520  *
 521  * To do so it opens the file and reads in the header information
 522  * if the extended header information is not presend it will
 523  * assume that that the file is a DOS executable.
 524  * If the extended header information is present it will
 525  * determine if the file is an 16 or 32 bit Windows executable
 526  * by check the flags in the header.
 527  *

 529  * file name extension; but Windows does it the same way ...
