Defined in header <cstdio>
void setbuf( std::FILE* stream, char* buffer );

Sets the internal buffer to use for I/O operations performed on the C stream stream.

If buffer is not null, equivalent to std::setvbuf(stream, buffer, _IOFBF, BUFSIZ)

If buffer is null, equivalent to std::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. If not null, must be able to hold at least BUFSIZ characters

[edit] Return value

(none)
