Hi,
there is a discrepancy in the documentation:
sys/syslimits.h says:
'/*
* We leave the following values undefined to force applications to
either
* assume conservative values or call sysconf() to get the current
value. *
* HOST_NAME_MAX
*
* (We should do this for most of the values currently defined here,
* but many programs are not prepared to deal with this yet.)
*/'
man gethostname says:
#include <unistd.h>
and
'Host names are limited to {HOST_NAME_MAX} characters, not including
the trailing null, currently 255.'
which makes people assume that HOST_NAME_MAX is defined in unistd.h.
What is the real idea? Keep gethostname compatible to the rest or force
users to call sysconf?
Should I file a bug report?
Erich
