+FUNCTION
+<<fsetpos64>>---restore position of a large stream or file
+
+INDEX
+	fsetpos64
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int fsetpos64(FILE *<[fp]>, const _fpos64_t *<[pos]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int fsetpos64(<[fp]>, <[pos]>)
+	FILE *<[fp]>;
+	_fpos64_t *<[pos]>;
+
+DESCRIPTION
+Objects of type <<FILE>> can have a ``position'' that records how much
+of the file your program has already read.  Many of the <<stdio>> functions
+depend on this position, and many change it as a side effect.
+
+You can use <<fsetpos64>> to return the large file identified by <[fp]> to a 
+previous position <<*<[pos]>>> (after first recording it with <<fgetpos64>>).
+
+See <<fseeko64>> for a similar facility.
+
+RETURNS
+<<fgetpos64>> returns <<0>> when successful.  If <<fgetpos64>> fails, the
+result is <<1>>.  The reason for failure is indicated in <<errno>>:
+either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
+64-bit repositioning) or <<EINVAL>> (invalid file position).
+
+PORTABILITY
+<<fsetpos64>> is a glibc extension.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek64>>, <<read>>, <<sbrk>>, <<write>>.
