Par2: 16/32 bit Disk type routines
1998-12-20 -- Roberto Artigas Jr.
 
Heavenes - The Get the Disk Type Routine has been discussed in several threads in C4/C5 for both 16 and 32 Bit. The Headers and Prototypes are already available. This is a routine right out of my library. It has been created out of code posted in this newgroup. It has been compiled and tested under 16 bit and 32 bit. Enjoy! Roberto Artigas Jr ========== sysDiskType PROCEDURE (xDriveName) ! Declare Procedure ! Start of "Data Section" ! [Priority 5000] DRIVE_UNKNOWN EQUATE( 0 ) DRIVE_NO_ROOT_DIR EQUATE( 1 ) DRIVE_FIXED EQUATE( 2 ) DRIVE_REMOVABLE EQUATE( 3 ) DRIVE_REMOTE EQUATE( 4 ) DRIVE_CDROM EQUATE( 5 ) DRIVE_RAMDISK EQUATE( 6 ) DriveName CSTRING(4) DriveType SHORT(0) DriveNumber SHORT(0) IRetVal SHORT(0) inregs LIKE(REGS) outregs LIKE(REGS) ! End of "Data Section" CODE ! Start of "Processed Code" ! [Priority 5000] !Pass drive name to Cstring DriveName = UPPER(xDriveName[1]) DriveNumber = INSTRING(DriveName[1], 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 1, 1) DriveName[2:3] = ':\' ! Get Drive Type ! Return string describing drive type. DriveType = GetDriveType(DriveName) ! ! This is 16Bit Code to determine if the DRIVE_REMOTE is a ! CDROM or a NETWORK drive. It checks for the existance of ! MSCDEX and then queries if the DriveNumber is a CD-ROM. ! OMIT('***',_Width32_) IF (DriveType = DRIVE_REMOTE) THEN inregs.wordregs.ax = 1500H inregs.wordregs.bx = 0 IRetVal = int86(2FH, inregs, outregs) IF (outregs.wordregs.bx <> 0) THEN inregs.wordregs.ax = 150BH inregs.wordregs.cx = DriveNumber - 1 IRetVal = int86(2FH, inregs, outregs) IF (outregs.wordregs.ax <> 0) THEN DriveType = DRIVE_CDROM END END END *** CASE (DriveType) OF DRIVE_UNKNOWN RETURN('0 - UNKNOWN') OF DRIVE_NO_ROOT_DIR RETURN('1 - NOROOTDIR') OF DRIVE_FIXED RETURN('2 - FIXED') OF DRIVE_REMOVABLE RETURN('3 - REMOVABLE') OF Drive_Remote RETURN('4 - NETWORK') OF DRIVE_CDROM RETURN('5 - CDROM') OF DRIVE_RAMDISK RETURN('6 - RAMDISK') END !
