(not specified in documentation) Note: while the function is executing, the following global descriptors are available: 20h stack segment 38h code segment of function 40h data alias for function's code segment additional GDT descriptors can be allocated using AH=02h with function "assign gdt" SeeAlso: AH=02h"VMiX",AH=51h"VMiX" --------T-1510------------------------------- INT 15 - MultiDOS Plus - TEST RESOURCE SEMAPHORE AH = 10h AL = semaphore number (00h-3Fh) Return: AH = status 00h semaphore not in use 01h semaphore owned by another task 02h invalid semaphore number 03h semaphore owned by caller SeeAlso: AH=02h"MultiDOS",AH=0Dh"MultiDOS",AH=1Dh"MultiDOS" --------Q-151000----------------------------- INT 15 - TopView - "PAUSE" - GIVE UP CPU TIME AX = 1000h Return: after other processes run Note: under DESQview, if the process issuing this call has hooked INT 08h, the current time-slice is set to expire at the next clock tick rather than immediately SeeAlso: AH=00h"MultiDOS",AX=5305h,INT 21/AH=89h,INT 21/AH=EEh"DoubleDOS" SeeAlso: INT 2F/AX=1680h,INT 60/DI=0106h,INT 62/AH=01h,INT 6F/AH=2Ah"F_YIELD" SeeAlso: INT 7A/BX=000Ah,INT 7F/AH=02h"MultiLink",INT 7F/AH=E8h --------Q-151001----------------------------- INT 15 - TopView - "GETMEM" - ALLOCATE "SYSTEM" MEMORY AX = 1001h BX = number of bytes to allocate Return: ES:DI -> block of memory or 0000h:0000h (DV v2.26+) AX = status (DV v2.42) 0000h successful 0001h failed Note: use SETERROR (AX=DE15h) to avoid a user prompt if there is insufficient common memory. Under DV v2.42, this call never generates a user prompt regardless of the SETERROR value; instead, it always returns AX=0001h and ES:DI=0000h:0000h if out of memory SeeAlso: AX=1002h,AX=102Eh,AX=DE0Ch,AX=DE15h --------Q-151002----------------------------- INT 15 - TopView - "PUTMEM" - DEALLOCATE "SYSTEM" MEMORY AX = 1002h ES:DI -> previously allocated block Return: block freed SeeAlso: AX=1001h,AX=DE0Dh --------Q-151003----------------------------- INT 15 - TopView - "PRINTC" - DISPLAY CHARACTER/ATTRIBUTE ON SCREEN AX = 1003h BH = attribute BL = character DX = segment of object handle for window Return: nothing Note: BX=0000h does not display anything, it only positions the hardware cursor to the logical cursor's current position --------Q-1510------------------------------- INT 15 - TopView - UNIMPLEMENTED IN DV 2.x AH = 10h AL = 04h thru 12h Return: pops up "Programming error" window in DV 2.x --------Q-151013----------------------------- INT 15 - TopView - "GETBIT" - DEFINE A 2ND-LEVEL INTERRUPT HANDLER AX = 1013h ES:DI -> FAR service routine Return: BX = bit mask indicating which bit was allocated 0000h if no more bits available SeeAlso: AX=1014h,AX=1015h Note: only a few TopView/DESQview API calls are allowed during a hardware interrupt; if other calls need to be made, the interrupt handler must schedule a 2nd-level interrupt with "SETBIT" (AX=1015h) --------Q-151014----------------------------- INT 15 - TopView - "FREEBIT" - UNDEFINE A 2ND-LEVEL INTERRUPT HANDLER AX = 1014h BX = bit mask from INT 15/AX=1013h Return: nothing SeeAlso: AX=1013h,AX=1015h --------Q-151015----------------------------- INT 15 - TopView - "SETBIT" - SCHEDULE ONE OR MORE 2ND-LEVEL INTERRUPTS AX = 1015h BX = bit mask for interrupts to post Return: indicated routines will be called: (DV 2.0x) at next task switch (DV 2.2x) immediately on return from hardware interrupt Notes: this is one of the few TopView calls which are allowed from a hardware interrupt handler the handler will be called with ES containing the segment of the handle of the next task to be executed; on return, ES must be the segment of a task handle SeeAlso: AX=1013h,AX=1014h --------Q-151016----------------------------- INT 15 - TopView - "ISOBJ" - VERIFY OBJECT HANDLE AX = 1016h ES:DI = possible object handle Return: BX = status FFFFh if ES:DI is a valid object handle (see #00414) 0000h if ES:DI is not Note: under DESQview versions prior to 2.50, an object handle is always a pointer to the object; for versions 2.50 and up, only task handles are always pointers--other handles may consist of a unique object number and offset into DESQview's common memory (see #00423) SeeAlso: AX=DE14h,AX=DE2Bh,AX=DE2Ch (Table 00413) Values for DESQview object type: 00h window/task 01h mailbox 02h keyboard 03h timer 04h pointer 05h panel 06h objectq Format of DESQview object: Offset Size Description (Table 00414) 00h WORD offset in common memory of previous object of same type 02h WORD offset in common memory of next object of same type 04h WORD signature FEDCh (DV 2.42-) signature FEDCh or object number (DV 2.50+) 06h WORD object type (see #00413) 08h DWORD object handle to return to caller 0Ch DWORD canonicalized object address (segment = common memory) 10h WORD offset in common memory of owning task (0000h for unowned OBJECTQs) 12h WORD mapping context offset in common memory of mapping context record (see #00416) remainder varies by object type and DESQview version ---v2.42 keyboard object--- 14h WORD flag bits (see also AH=12h/BH=0Ah"OBJECT") bit 15: keyboard opened 16h 4 BYTEs ???

switched Notes: this call may not be nested; a second call must be preceded by a call to "USTACK" (AX=1025h) while TopView requires many API calls to be executed while on the task's internal stack, DESQview allows those calls to be executed regardless of the current stack SeeAlso: AX=1025h --------Q-15101B----------------------------- INT 15 - TopView - "BEGINC" - BEGIN CRITICAL REGION AX =

window for that task) Return: indicated task will not get any CPU time until restarted with AX=101Eh Note: once a task has been stopped, additional "STOP"s are ignored BUG: in DV 2.00, this function is ignored unless the indicated task is the current task SeeAlso: AX=101Eh,AX=102Bh,AH=12h"VMiX",INT 21/AH=81h --------Q-15101E----------------------------- INT 15 - TopView - "START" - START TASK AX

jump to next time task is run Return: nothing Notes: the FAR routine is entered with the current ES, DS, SI, DI, and BP values, using the task's internal stack (see AX=101Ah); only SS:SP needs to be preserved multiple PGMINTs to a single task are processed last-in first-out if the other task is in a DOS or DV API call, the interruption will occur on return from that call --------Q-151022BX0000----------------------- INT 15 - TopView - "GETVER" - GET VERSION AX = 1022h BX = 0000h Return: BX nonzero, TopView or compatible loaded (BL = major version, BH = minor version)
