[Edit] Sorry, forgot that I posted about this before -> viewtopic.php?f=43&t=78145

Code: Select all

// !db 'ProcessIdToSessionId',0x0
db 'ProcessIdToSessionId',0x0

"db 'ProcessIdToSessionId',0x0" is valid programming code in FASM, but unfortunately not in C programming language.

There are already some codes here that generate different code with CompilerIf options for ASM and C-backend.

Unfortunately, I also see some that implement ASM adapted in C-backend. But these codes do not run on ARM processors. And when the first PB version for Window ARM comes (is planned in the futures), then the problems with ASM will start again.

[Fred]

PB ARM uses the C backend, so it shouldn't be an issue if you write a C version of your subroutine

[mk-soft]

I am aware of that,

but some people put ASM-Intel commands in the c-backend, which then leads to errors on ARM.
I just wanted to remind you that this is not a good way.

[Fred]

Ho yes, you're totally right here.
