This section describes the interface changes made to the iostream library to make it MT-Safe.
The following table lists the new classes added to the libC interfaces.
stream_MT stream_locker unsafe_ios unsafe_istream unsafe_ostream unsafe_iostream unsafe_fstreambase unsafe_strstreambase |
The following table lists the new class hierarchy added to the iostream interfaces.
class streambuf: public stream_MT {...}; class unsafe_ios {...}; class ios: virtual public unsafe_ios, public stream_MT {...}; class unsafe_fstreambase: virtual public unsafe_ios {...}; class fstreambase: virtual public ios, public unsafe_fstreambase {...}; class unsafe_strstreambase: virtual public unsafe_ios {...}; class strstreambase: virtual public ios, public unsafe_strstreambase {...}; class unsafe_istream: virtual public unsafe_ios {...}; class unsafe_ostream: virtual public unsafe_ios {...}; class istream: virtual public ios, public unsafe_istream {...}; class ostream: virtual public ios, public unsafe_ostream {...}; class unsafe_iostream: public unsafe_istream, public unsafe_ostream {...}; |
The following table lists the new functions added to the iostream interfaces.
