Remarks

These constants represent the type of buffer for setvbuf.

The possible values are given by the following manifest constants:

Constant	Meaning
`_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`.
