Re: [Quickfix-developers] Upgrading to quickfix 1.12.4:C++/MySQLConnection.h:98: warning: suggest parentheses aroundassignment used, as truth value
|

Maybe the question is that it should be an assignment or not.
The entire function is:
char* getValue( int row, int column )
{
if( m_rows.empty() )
{
MYSQL_ROW row =3D 0;
while ( row =3D mysql_fetch_row( m_result ) )
m_rows.push_back(row);
}
return m_rows[row][column];
}
so it seems to be an assignment.
This file is inside quickfix-1.12.4. No one has changed this file, or=20
are there a newer version that fix this problem?
