streamsize in_avail();
Returns: If a read position is available, returnsegptr() - gptr().
Otherwise returnsshowmanyc().
int_type snextc();
Effects: Callssbumpc().
Returns: If that function returnstraits::eof(), returnstraits::eof().
Otherwise, returnssgetc().
int_type sbumpc();
Effects: If the input sequence read position is not available, returnsuflow().
Otherwise, returnstraits::to_int_type(*gptr()) and increments the next pointer for the input sequence.
int_type sgetc();
Returns: If the input sequence read position is not available, returnsunderflow().
Otherwise, returnstraits::to_int_type(*gptr()).
streamsize sgetn(char_type* s, streamsize n);
Returns: xsgetn(s, n).
