[dpdk-dev] [PATCH] EAL: add format(printf) attrib. to appropriate fns
Bruce Richardson
bruce.richardson at intel.com
Tue Jun 17 20:42:42 CEST 2014
Mark the rte_log, cmdline_printf and rte_snprintf functions as
being printf-style functions. This causes compilation errors
due to mis-matched parameter types, so the parameter types are
fixed where appropriate.
