+FUNCTION
+<<setbuffer>>---specify full buffering for a file or stream with size
+
+INDEX
+	setbuffer
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	void setbuffer(FILE *<[fp]>, char *<[buf]>, int <[size]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	void setbuffer(<[fp]>, <[buf]>, <[size]>)
+	FILE *<[fp]>;
+	char *<[buf]>;
+	int <[size]>;
+
+DESCRIPTION
+<<setbuffer>> specifies that output to the file or stream identified by
+<[fp]> should be fully buffered.  All output for this file will go to a
+buffer (of size <[size]>).  Output will be passed on to the host system
+only when the buffer is full, or when an input operation intervenes.
+
+You may, if you wish, supply your own buffer by passing a pointer to
+it as the argument <[buf]>.  It must have size <[size]>.  You can
+also use <<NULL>> as the value of <[buf]>, to signal that the
+<<setbuffer>> function is to allocate the buffer.
+
+WARNINGS
+You may only use <<setbuffer>> before performing any file operation
+other than opening the file.
+
+If you supply a non-null <[buf]>, you must ensure that the associated
+storage continues to be available until you close the stream
+identified by <[fp]>.
+
+RETURNS
+<<setbuffer>> does not return a result.
+
+PORTABILITY
+This function comes from BSD not ANSI or POSIX.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
+
+
+FUNCTION
+
+<<setlinebuf>>---specify line buffering for a file or stream
+
+INDEX
+	setlinebuf
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	void setlinebuf(FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	void setlinebuf(<[fp]>)
+	FILE *<[fp]>;
+
+DESCRIPTION
+<<setlinebuf>> specifies that output to the file or stream identified by
+<[fp]> should be line buffered.  This causes the file or stream to pass
+on output to the host system at every newline, as well as when the
+buffer is full, or when an input operation intervenes.
+
+WARNINGS
+You may only use <<setlinebuf>> before performing any file operation
+other than opening the file.
+
+RETURNS
+<<setlinebuf>> returns as per setvbuf.
+
+PORTABILITY
+This function comes from BSD not ANSI or POSIX.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
