My bug report against the current POSIX draft was accepted. For the
record, here are the changes being made. (``The indicated line'' is
referring to a line in the definition of gethostname() where the
length of the buffer was previously defined to be 256, including the
terminating null. The excluding-null semantics were chosen for
parallel construction with {NAME_MAX} and similar constants.
At the indicated line, for 255 substitute {HOST_NAME_MAX}.
At XBD page 261 (<limits.h>) before line 8966 insert:
{HOST_NAME_MAX}
Maximum length of a host name (not including the terminating
null) as returned from the gethostname() function.
Minimum acceptable value: {_POSIX_HOST_NAME_MAX}
Before line 9183, insert:
{_POSIX_HOST_NAME_MAX}
Maximum length of a host name (not including the terminating
null) as returned from the gethostname() function.
Value: 255
At XBD page 424 (<unistd.h>) before line 14818 insert:
_SC_HOST_NAME_MAX
At XSH page 1982 (sysconf()) before line 45530 insert:
{HOST_NAME_MAX} _SC_HOST_NAME_MAX
I include the last two changes for completeness only; I do not
believe that applications are likely to use the sysconf() interface
for this purpose.
