Hi NG,
I have a library of which I want to change the name of a specific method
so it is more intuitive. I plan to keep the old method in there for now
so I won't break any existing code. But I would like to get a compile
time warning when this method is called. That way a programmer using
this library sees the warning and can change his/her code.
Is this possible and if yes, how?
Thanks in advance,
Mark

There is no standard way.
However, most compiler offer a pragma that can do
that.
Eg. in VC++ a line
#pragma message( "Attention" )
will output the text "Attention" during compilation.
You could now
rename the function in the library
using a macro, replace any call to the function with
the sequence
#pragma message( "Warning: old function call, use XXX instead" )
call renamed function

In the header file do;
#ifdef ENABLE_DEPRECAT ED
Foo YourOldStupidFr oo(..);
#endif

Since the OP didn't say which compiler he's using, but seems to have posted
from a Linux system, I'll just show the g++ way, too. It defines a specific
function attribute for this that you can use like:
void my_function() __attribute__(( deprecated));
Then the compiler will issue a warning on use of that function. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

What is wrong with the following code? My compiler (GCC) produces a warning
which states that the initialisation values of a local struct are "not

suggests that the code is at least questionable. I do not see anything
questionable...
This program demonstrates the issue. I get the warning whenever I pass a

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
