Due to historical accidents which the LWG refuses to correct, the I/O library suffers from a design error: this function is hidden in derived classes by overrides of the zero-argument rdbuf()
, which is non-virtual for hysterical raisins. As a result, you must use explicit qualifications to access this function via any derived class. For example:
std::fstream foo; // or some other derived type std::streambuf* p = .....; foo.ios::rdbuf(p); // ios == basic_ios<char>

int std::ios_base::xalloc | ( | ) | throw () [static, inherited] |
Access to unique indices.
The implementation maintains a static variable that is incremented and returned on each invocation. xalloc is guaranteed to return an index that is safe to use in the iword and pword arrays.
long& std::ios_base::iword | ( | int | __ix | ) | [inline, inherited] |
Access to integer array.
__ix | Index into the array. |
The implementation reserves several indices. You should use xalloc to obtain an index that is safe to use. Also note that since the array can grow dynamically, it is not safe to hold onto the reference.
