Subject: Don't allow mkfifo to create files such as "--help"
X-Git-Tag: 0_45~84
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=46a38dbb9b1a5ecec99dda2eb42b456e5ac76c26;p=oweals%2Fbusybox.git

Don't allow mkfifo to create files such as "--help"

This patch checks if the name of FIFO to be created begins with "-" and
calls usage() if it does.

Regards,
Pavel Roskin
