The variable optind should be reset to one not zero. From the man page: "The variable optind is the index of the next element to be processed in argv. The system initializes this value to 1. The caller can reset it to 1 to restart scanning of the same argv, or when scanning a new argument vector.” The problem I saw with my application was trying to parse the wrong option, which can happen as DPDK parses the first part of the command line and the application parses the second part. If you call getopt() multiple times in the same execution, the behavior is not maintained when using zero for optind. Signed-off-by: Keith Wiles <keith.wiles@intel.com> |
