The protected member function returns zero if the file pointer fp is a null pointer.

설명

setbuf calls setvbuf(fp, (char *)_Buffer, _IOFBF, _Count * sizeof (Elem) ) to offer the array of _Count elements beginning at _Buffer as a buffer for the stream. If that function returns a nonzero value, the function returns a null pointer. Otherwise, it returns this to signal success.
