Re: [Xenomai-core] [PATCH 5/6] Overread dev-prefix on posix open

2006-06-28 Thread Jan Kiszka 
Update to fix a compiler warning (char * vs. const char *).

Subject: Overread dev-prefix on posix open

Adds support to the posix user-space lib to address RTDM-devices also with a (here meaningless) "/dev/" name prefix. Intended to increase user convenience slightly.
