Eljay,
'isalnum' is not my function, it is the part of namespace std and the GNU
project, right?
Compiler says that isalnum is not declared in the following line in cctype:
namespace std
{
using ::isalnum;
...
}
I think this is very embarrassing. Doesn't cctype refer to all the
necessary files, including the one that defines isalnum?
Thanks,
Nikolai

|
| In C++, this is a C++ declaration:
|
| extern int isalnum(int Ch);
|
| When compiled, it will result in a C++ mangled symbol:
| __Z7isalnumi
| (depending on the platform; expect variations)
|
| In C++, this is a C declaration:
| extern "C" int isalnum(int Ch);
|
| When compiled, it will result in a C symbol:
| _isalnum
| (or just isalnum on some platforms)
|
| That's possibly why the compiler is not seeing your 'isalnum' in cctype.
