Added new functions to EXE module

[RobertoBianchi]

Hi,

I've been added the EXE_PE_GetHeapReserve(), EXE_PE_GetHeapCommit(), EXE_PE_GetStackReserve() and EXE_PE_GetStackCommit functions to the EXE module.
You'll find this update in the next ThinBasic release.
Here is a test script:

nItems = LL_Count(pList)

IF nItems > 0 THEN
FOR Count = 1 TO nItems
INCR nFiles
FileName = LL_GetItem(pList, Count)
eStackR = EXE_PE_GetStackReserve(FileName)
' Skip some unpleasant files
if eStackR < 0 then
incr nSkippedFiles
else
eStackC = EXE_PE_GetStackCommit(FileName)
eHeapR = EXE_PE_GetHeapReserve(FileName)
eHeapC = EXE_PE_GetHeapCommit(FileName)
geStackR += eStackR
geStackC += eStackC

geHeapC += eHeapC
console_writeLine(Lset$(Filename, %MY_MAXPATH) & ":" & hex$(eStackR,6) & " " & hex$(eStackC, 6) & " " & hex$(eHeapR, 6) & " " & Hex$(eHeapC, 6))
end if
NEXT
END IF

END SUB

Thanks Roberto,

what does heap reserve mean for example, is it some preallocated memory space when application starts up?


Thanks,
Petr

[RobertoBianchi]

Yes Petr, more precisely:

SizeOfStackReserve is the amount of virtual memory to reserve for the initial thread's stack, however not all of this memory is committed but only the amount specified by the SizeOfStackCommit field. For example this field is what PB fills with the value specified after the #STACK metastatement.

SizeOfStackCommit is the amount of memory initially committed for the initial thread's stack.

SizeOfHeapReserve is the amount of virtual memory to reserve for the initial process heap. This heap's handle can be obtained by calling GetProcessHeap. Like as for the stack not all of this memory is committed but only the amount specified by the SizeOfHeapCommit field. Recently I had some problems with the process heap in ThinAir.

SizeOfHeapCommit is the amount of memory initially committed in the process heap.
