The setvbuf function defines the storage area pointed to by buf so that it can be
used as an input/output buffer area for the stream input/output file indicated by
file pointer fp.
There are three ways of using this buffer area, as follows:
The buffer area must not be released before the opened stream input/output file
is closed. Also, the setvbuf function must be used between opening of the
stream input/output file and execution of input/output processing,
Input/output is fully buffered.
Input/output is line buffered. That is, input/output data is fetched from the
buffer area when a new-line character is written, when the buffer area is
full, or when input is requested.
Input/output is unbuffered.
The setvbuf function usually returns 0. However, when an illegal value is
specified for type or size, or when the request on how to use the buffer
could not be accepted, a value other than 0 is returned.
