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

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.

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

Return value

None.
