Sets the internal buffer to use for stream operations. It should be at least BUFSIZ characters long.
If buffer is not null, equivalent to setvbuf(stream, buffer, _IOFBF, BUFSIZ)
If buffer is null, equivalent to setvbuf(stream, NULL, _IONBF, 0), which turns off buffering.
[edit] Parameters
stream | - | the file stream to set the buffer to |
buffer | - | pointer to a buffer for the stream to use. If NULL is supplied, the buffering is turned off |
