+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>>.
