std::basic_stringbuf<CharT,Traits,Allocator>::init_buf_ptrs
Min standard notice:
Initializes the input and output sequences from buf according to mode. buf and mode are exposition-only data members of *this.
# Declarations
void init_buf_ptrs();
(exposition only*)
# Notes
For efficiency reasons, stream buffer operations can violate invariants of buf while it is held encapsulated in the std::basic_stringbuf, e.g., by writing to characters in the range [buf.data() + buf.size(),buf.data() + buf.capacity()).
All operations retrieving a std::basic_string from buf ensure that the std::basic_string invariants hold on the returned value.
