Name
_IOFBF macro — Full buffering
Synopsis
int _IOFBF
When passed as the mode
parameter to setvbuf
, the
_IOFBF
macro sets an open file to
full buffering. A buffer is flushed when it is full. The _IOFBF
macro expands to a constant
integer.
Support for fully-buffered streams is
implementation-dependent.
