How to clear just the eof flag of a file stream

[wtf]

i tried doing this:

if ( (file.rdstate() & fstream::eofbit) != 0 )
    file.clear(fstream::eofbit);

But it does not seem to work.

[wtf]

I don't want to clear all the states, just the eofbit state.

Thank you very much.

would this do it:

if ( (file.rdstate() & fstream::eofbit) != 0 )
        file.clear(file.rdstate() & fstream::failbit & fstream::badbit & fstream::goodbit);

XOR: file.clear( file.rdstate() ^ fstream::eofbit ); will toggle the eofbit
AND NOT: file.clear( file.rdstate() & ~fstream::eofbit ); will toggle set eofbit to 0 in any case
