Subject: mined: increase the size of the tgetent() buffer.
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/zpipe.c?a=commitdiff_plain;h=79444d163df08aae0f3a8c3181fbeb0781be144d;p=minix.git

mined: increase the size of the tgetent() buffer.

From the termcap section of the GNU termutils manual:

"There is no way you can tell how much space is needed, so the convention
is to allocate a buffer 2048 characters long and assume that is enough.
(Formerly the convention was to allocate 1024 characters and assume that
was enough. But one day, for one kind of terminal, that was not
enough.)"
