| #inline |

I am using PIC16F877A, compiler version 3.190
When I use the "#inline" as follows:
#inline
void TxPacket(BYTE *Descriptor)
{
}
I get the error: Function definition different from previous definition
The function delared as: void TxPacket(BYTE *Descriptor);
Any ideas?

You need to add #inline to the definition as well.

Which definition?
Where I declare the function you mean?

If I add the #inline to the function declaration as well:
#inline
void TxPacket(BYTE *Descriptor);
I get the following error:
Out of ROM, A segment or the program is too large

Right, I have solved it, I just had too large function.
I have splited it to a few smaller, and no problems then.
The next question is, can I use #inline only for functions, or I can use it for a separete row only as well?
What else does it effect except the speed?

It is for functions. Not sure what you mean by "row" unless you mean line of code which is of course "inline".
Tells the compiler that the function immediately following the directive is to be implemented INLINE. This will cause a duplicate copy of the code to be placed everywhere the function is called. This is useful to save stack space and to increase speed. Without this directive the compiler will decide when it is best to make procedures INLINE. |
