// TESTING 'sputn' METHOD

// Concerns:
//: 1 Strings of varying length are written correctly.
//:
//: 2 Writing strings does not overwrite existing buffer content.
//:
//: 3 No more than the specified number of characters are written.
//:
//: 4 No writing happens beyond existing capacity.
//
// Plan:
//: 1 Write out representative strings from the categories 0
//: characters, 1 character, and > 1 character, into streambufs with
//: representative contents "empty", substantially less than
//: capacity, and almost-full-so-that-next-write-exceeds-capacity.
//: (C-1..4)
//
// Testing:
// streamsize sputn(const char_type, streamsize);
