protected member function
Pointer to beginning of input sequence
Returns a pointer to the first element of the array with the portion of the controlled input sequence that is currently buffered.
Members function can access this array directly; It is described by the pointers returned by the following protected member functions:
|eback()||Beginning of the buffered part of the input sequence|
|gptr()||Current position in the input sequence ("get pointer")|
|egptr()||End of the buffered part of the input sequence|
A pointer to the beginning of an array with the part of the controlled input sequence that is currently buffered.
Accesses the stream buffer object.
Concurrent access to the same stream buffer object may cause data races.
Strong guarantee: if an exception is thrown, there are no changes in the stream buffer.
