.SH NAME
pread, pwrite \- read from or write to a file descriptor at a given offset
.SH SYNOPSIS
.SH CONFORMING TO
POSIX.1-2001.
.SH NOTES
+The
+.BR pread ()
+and
+.BR pwrite ()
+system calls are especially useful in multithreaded applications.
+They allow multiple threads to perform I/O on the same file descriptor
+without being affected by changes to the file offset by other threads.
+
On Linux, the underlying system calls were renamed
in kernel 2.6:
.BR pread ()
.BR read (2),
.BR readv (2),
.BR write (2)
