Add a throwaway define for SOPT_SIZE_CMSG_IFINDEX_IPV4 for systems which have neither IP_RECVIF nor IP_PKTINFO (eg openbsd). + * command.h: Cleanup the defines a bit, add helper defines and + collapse all defines to use those. Add an attribute field to + cmd_element to support, eg hidden or deprecated commands, add + defun defines for such. All that's left to do is add logic + to command.c to check these attributes... ;) 2004-10-19 Hasso Tepper <hasso at quagga.net> diff --git a/lib/command.h b/lib/command.h index 8a17bbb4..d357698d 100644 --- a/lib/command.h +++ b/lib/command.h @@ -125,6 +125,12 @@ struct cmd_node vector cmd_vector; }; +enum +{ + CMD_ATTR_DEPRECATED, + CMD_ATTR_HIDDEN, +}; + /* Structure of command element. */ struct cmd_element { @@ -136,6 +142,7 @@ struct cmd_element unsigned int cmdsize; /* Command index count. */ char *config; /* Configuration string */ vector subconfig; /* Sub configuration string */ + u_char attr; /* Command attributes */ }; /* Command description structure. */ @@ -164,17 +171,40 @@ struct desc /* Turn off these macros when uisng cpp with extract.pl */ #ifndef VTYSH_EXTRACT_PL -/* DEFUN for vty command interafce.
