In the program I am converting from C to VB, there is what I understand is called "Inline Assembly".
Can someone give me some information on how this is possible or what I could do to accomplish this in another language?
Could they be made into a DLL?
Thanks for any leads!
Inline assembly is when you paste assembler code in your C source by way of a keyword. This is very compiler specific, so it is not portable to use:
I recommend searching google for the details of inline assembly for your compiler and system.Code:int main ( void ) { __asm { /* ** Assembler code goes here. */ } return 0; }
-Prelude
My best code is written with the delete key.
Your example is identical to the what I am seeing in this portion of the C code.
Now knowing that this code is probably not portable, what options do I have for performing the same operation?
Would it be best to build a DLL with these two small functions and make a call, or are there libraries out there that are already suffcient for this?
The Inline ASM is very simple, here it is:
How else could I accomplish the same thing??Code:// wait for low do { asm { xor ax,ax mov dx,card_addr in al,dx mov port_data,ax } } while ((port_data & 0x01) == 1); // wait for high do { asm { xor ax,ax mov dx,card_addr in al,dx mov port_data,ax } } while ((port_data & 0x01) == 0);
Thanks again for your specifics, as they have helped me to understand tremendously.
Sure, ASM is simple if you know ASM. Since you're going to VB from C, you naturally don't care about performance. As such, throw together some pseudocode to what the ASM is doing, and turn it into a function.The Inline ASM is very simple, here it is:
Quzah.
Hope is the first step on the road to disappointment.
Cool... I understand and will try and implement this method.
Thanks for your help.
