-FUNCTION
-<<pread64>>---read a large file from specified position
-
-INDEX
- pread64
-
-ANSI_SYNOPSIS
- #include <unistd.h>
- ssize_t pread64(int <[fd]>, void *<[buf]>, size_t <[n]>, loff_t <[off]>);
-
-TRAD_SYNOPSIS
- #include <unistd.h>
- ssize_t pread64(<[fd]>, <[buf]>, <[n]>, <[off]>)
- int <[fd]>;
- void *<[buf]>;
- size_t <[n]>;
- loff_t <[off]>;

-DESCRIPTION
-The <<pread64>> function is similar to <<pread>>. The only difference is
-that it operates on large files and so takes a 64-bit offset. Like <<pread>>>,
-the file position is unchanged by the function (i.e. the file position
-is the same before and after a call to <<pread>>).
-
-RETURNS
-<<pread64>> returns the number of bytes read or <<-1>> if failure occurred.
-
-PORTABILITY
-<<pread64>> is an EL/IX extension.
-
-Supporting OS subroutine required: <<read>>, <<lseek64>>.
