            Bug ID: 97491
           Summary: sendfile man page should mention short "sends"
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
          Assignee: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
          Reporter: gjasny-S0/GAf8tV78@public.gmane.org
        Regression: No

Hello,

Linux 3.16 (3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt4-1, glibc 2.19-18) seems to
truncate larger requests to 2G (file to file copy):

strace output:
  sendfile(4, 3, [0], 10240000000)        = 2147479552


I know one should expect this behavior from read/write calls but for sendfile
it was somehow unexpected.

Maybe you could mention that fact in the man page for sendfile?

Thanks,
Gregor
