These constants represent the type of buffer for setvbuf.
The possible values are given by the following manifest constants:
|_IOFBF||Full buffering: Buffer specified in call to setvbuf is used and its size is as specified in setvbuf call. If buffer pointer is NULL, automatically allocated buffer of specified size is used.|
|_IOLBF||Same as _IOFBF.|
|_IONBF||No buffer is used, regardless of arguments in call to setvbuf.|
