write(2) man page missing error code

write(2) man page missing error code

[Sutin, Brian M HS]

Manpages-dev 3.23-1
Linux 2.6.32-24
Ubuntu Lucid

I am getting the error code EDESTADDRREQ from a write() to a udp port.  It isn't mentioned in the man page as a possibility.

Thanks for the report. For upstream man-pages-3.26, I added the following

--- a/man2/write.2
+++ b/man2/write.2
@@ -128,6 +128,11 @@ so a portable application should check for both
possibilities.
 .I fd
 is not a valid file descriptor or is not open for writing.
 .TP
+.B EDESTADDRREQ
+.I fd
+refers to a datagram socket for which a peer address has not been set using
+.BR connect (2).
+.TP
 .B EFAULT
 .I buf
 is outside your accessible address space.


Cheers,

Michael
