//: 1 Manually call 'pubsetbuf' method and verify that the buffer has
//: been reset to the new address and length. (C-1..2)

//: 2 Verify that, in appropriate build modes, defensive checks are
//: triggered for invalid attribute values, but not triggered for
//: adjacent valid ones (using the 'BSLS_ASSERTTEST_*' macros). (C-3)
//
// Testing:
// FixedMemOutput *pubsetbuf(char *buffer, streamsize length);
