        large files.
        (stmp-stdio64,stdio64.texi): New targets to optionally add in

        for 64-bit offset large file support.
        (__FILE): New intermediate type either set to struct __sFILE64 or

+
+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 <<fgetpos64>> to report on the current position for a file
+identified by <[fp]> that was opened by <<fopen64>>; <<fgetpos>> will write 
+a value representing that position at <<*<[pos]>>>.  Later, you can
+use this value with <<fsetpos64>> to return the file to this
+position.
+
+In the current implementation, <<fgetpos64>> simply uses a character
+count to represent the file position; this is the same number that
+would be returned by <<ftello64>>.
+
+RETURNS
+<<fgetpos64>> returns <<0>> when successful.  If <<fgetpos64>> fails, the
+result is <<1>>.  Failure occurs on streams that do not support
+positioning or streams not opened via <<fopen64>>; the global <<errno>> 
+indicates these conditions with the value <<ESPIPE>>.
+
+PORTABILITY
+<<fgetpos64>> is a glibc extension.
+
+No supporting OS subroutines are required.

+
+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 <<fseeko64>> to set the position for the file identified by
+<[fp]> that was opened via <<fopen64>>.  The value of <[offset]> determines 
+the new position, in one of three ways selected by the value of <[whence]> 
+(defined as macros in `<<stdio.h>>'):
+
+<<SEEK_SET>>---<[offset]> is the absolute file position (an offset
+from the beginning of the file) desired.  <[offset]> must be positive.
+
+<<SEEK_CUR>>---<[offset]> is relative to the current file position.
+<[offset]> can meaningfully be either positive or negative.
+
+<<SEEK_END>>---<[offset]> is relative to the current end of file.
+<[offset]> can meaningfully be either positive (to increase the size
+of the file) or negative.
+
+See <<ftello64>> to determine the current file position.
+
+RETURNS
+<<fseeko64>> returns <<0>> when successful.  On failure, the
+result is <<EOF>>.  The reason for failure is indicated in <<errno>>:
+either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
+repositioning or wasn't opened via <<fopen64>>) or <<EINVAL>> 
+(invalid file position).

+@chapter Large File Input and Output (@file{stdio.h}) 
+
+This chapter comprises additional functions to manage large files which
+are potentially larger than 2GB.
+
+The underlying facilities for input and output depend on the host
+system, but these functions provide a uniform interface.
+
+The corresponding declarations are in @file{stdio.h}.

+INDEX

+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile64(void);
+
+	FILE *_tmpfile64_r(void *<[reent]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile64();
+
+	FILE *_tmpfile64_r(<[reent]>)
+	char *<[reent]>;
+
+DESCRIPTION
+Create a large temporary file (a file which will be deleted automatically),
+using a name generated by <<tmpnam>>.  The temporary file is opened with
+the mode <<"wb+">>, permitting you to read and write anywhere in it
+as a binary file (without any data transformations the host system may
+perform for text files).  The file may be larger than 2GB.
+
+The alternate function <<_tmpfile64_r>> is a reentrant version.  The
+argument <[reent]> is a pointer to a reentrancy structure.
+
+Both <<tmpfile64>> and <<_tmpfile64_r>> are only defined if __LARGE64_FILES
+is defined.
+
+RETURNS
+<<tmpfile64>> normally returns a pointer to the temporary file.  If no
+temporary file could be created, the result is NULL, and <<errno>>
+records the reason for failure.
+
+PORTABILITY
+<<tmpfile64>> is a glibc extension.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
+<<isatty>>, <<lseek64>>, <<open64>>, <<read>>, <<sbrk>>, <<write>>.
+
+<<tmpfile64>> also requires the global pointer <<environ>>.
