Package: manpages-dev Version: 1.39-1.1
The man page for send(2) contains the following incorrect statement in the Errors section:
ENOBUFS
The output queue for a network interface was full.
This generally indicates that the interface has
stopped sending, but may be caused by transient
congestion. (This cannot occur in Linux, packets
are just silently dropped when a device queue over
flows.)The erroneous bit is "This cannot occur in Linux", because it certainly can, and I've had sendto() fail with this error in my own program when the ARP cache filled up.
An example of code in the Kernel which can return this error is In net/core/neighbour.c:
n = neigh_alloc(tbl);
if (n == NULL)
return ERR_PTR(-ENOBUFS);I'm using Debian 3.0r5 ("Woody") with Kernel 2.4.29 on i386--
