Subject: rpcgen(1): default to "STDIN" as input file when compiling to headers.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=134d7b1ef94ae6f4f6ffb58b17fcd2643c6ae9ac;p=openbsd

rpcgen(1): default to "STDIN" as input file when compiling to headers.

FreeBSD, NetBSD, and GNU all use a variation of "STDIN" as the
default input filename when compiling to header files (-h) to prevent
a NULL-pointer deference. Adopt a similar approach.
