Thank you.

Maybe you are doing something wrongly for crashing fbide. But what ???
Try adding -v (verbose mode) when compiling with fbc like that there is always something to display.

If you are using a batch file you can test %errorlevel%
Compilation successful --> %errorlevel% = 0 otherwise --> %errorlevel% = 1

IF %ERRORLEVEL% NEQ 0 Echo An error was found
IF %ERRORLEVEL% EQU 0 Echo No error found

Use goto to skip lines

Hi speedfixer,

WIN32 doesn't refer to Windows 32bit but just windows API so 32bit or 64bit, it's like that everywhere, not only in fbc. Win64 is almost never used.
In a same way you don't have __FB_LINUX32__ and __FB_LINUX64__

So the way of doing is correct : testing Win32 and Is64bit.

If you want to retrieve byte by byte you need to define a byte pointer. To avoid warning just cast it dim as byte ptr numptr NumPtr = cast(byte ptr,@Number) If you don't do that you get an integer value (4 bytes if under 32bit) and every time you add 1 to the pointer the real value is increased by 4...

You must use a byte ptr instead an integer ptr otherwise an integer is retrieved every turn in the loop.... Just add a 'print numptr' to see that. Dim Number as uLong Dim NumPtr as byte ptr ''<------------------------ Dim Index as byte Number = &H12345678 NumPtr = CInt(@Number) 'If I want to see...

To say it more clearly. All the additions below should take the same amount of time with a 64 bit processor: You have to take in account also the compiler : 32bit or 64bit. With the 64bit version of fbc the additions (and other operations) are done using 64bit integer so it's necessary to convert b...

Profiling allows to know how much CPU time is used by every procedure for eventually choose where optimize. It's experimental. Give me your opinion. Use : - compile your code as usually with the provided exe. Just add the option -profile (don't forget -gen gas64). http://users.freebasic-portal.de/sa...

I read also this but it's more like an example for finding an explicit name.

GetCurrentThread Windows's API :-)

"handle" thanks

The meaning of ThreadSelf is not obvious, at least for me.
ThreadGetHandle() (a bit long) or ThreadHandle() seem clearer.

And keep "handle" everywhere as it's its purpose.

Hi robert, I don't use makefiles so my answer is what I understand after looking them. For fbc preferably use ALLFBCFLAGS += -gen gas64 As FBFLAGS is also used for linking. You could add -R and if you see a64 files the compiler uses gas64. For the tests use the option 'GEN' with makefile for selecti...

Hi UEZ,

Put this line like before the test
You will see values reaching limits --> undefined.
I guess (no time to go deeper) that the order of the values for the test is important.
