Returns a pointer to the element just past the last element of the array with the portion of the controlled output sequence that is currently buffered.
Member functions can access this array directly; It is described by the pointers returned by the following protected member functions:
Member type char_type is the type of the characters in the stream buffer (the first class template parameter).
Concurrent access to the same stream buffer object may cause data races.

Pointer to end of output sequence
Member functions can access this array directly; It is described by the pointers returned by the following protected member functions:
| member | descritpion |
|---|---|
| pbase() | Beginning of the buffered part of the output sequence |
| pptr() | Current position in the output sequence ("put pointer") |
| epptr() | End of the buffered part of the output sequence |
Parameters
noneReturn Value
A pointer to the past-the-end element of an array with the part of the controlled output sequence that is currently buffered.Member type char_type is the type of the characters in the stream buffer (the first class template parameter).
Data races
Accesses the stream buffer object.Concurrent access to the same stream buffer object may cause data races.
Exception safety
Strong guarantee: if an exception is thrown, there are no changes in the stream buffer.See also
