/** Return a string representing the contents of a buffer sequence.
|
|
This function returns a string representing an entire buffer
|
sequence. Nulls and unprintable characters in the buffer
|
sequence are inserted to the resulting string as-is. No
|
character conversions are performed.
|
|
@param buffers The buffer sequence to convert
|
|
@par Example
|
|
This function writes a buffer sequence converted to a string
|
to `std::cout`.

|
