Defined in header <stdio.h>
void setbuf( FILE          *stream, char          *buffer );
(until C99)
void setbuf( FILE *restrict stream, char *restrict buffer );
(since C99)

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

[edit] Return value

None.
