- * Register a new command with the core.
- *
- * The command will only happen if commands are enabled,
- * which is a UI pref. UIs don't have to support commands at all.
- *
- * @param cmd The command. This should be a UTF8 (or ASCII) string, with no spaces
- * or other white space.
- * @param args This tells Purple how to parse the arguments to the command for you.
- * If what the user types doesn't match, Purple will keep looking for another
- * command, unless the flag @c PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed in f.
- * This string contains no whitespace, and uses a single character for each argument.
- * The recognized characters are:
- * 'w' Matches a single word.
- * 'W' Matches a single word, with formatting.
- * 's' Matches the rest of the arguments after this point, as a single string.
- * 'S' Same as 's' but with formatting.
- * If args is the empty string, then the command accepts no arguments.
- * The args passed to callback func will be a @c NULL terminated array of null
- * terminated strings, and will always match the number of arguments asked for,
- * unless PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed.
- * @param p This is the priority. Higher priority commands will be run first, and usually the
- * first command will stop any others from being called.
- * @param f These are the flags. You need to at least pass one of PURPLE_CMD_FLAG_IM or
- * PURPLE_CMD_FLAG_CHAT (can may pass both) in order for the command to ever actually
- * be called.
- * @param prpl_id This is the prpl's id string. This is only meaningful if the proper flag is set.
- * @param func This is the function to call when someone enters this command.
- * @param helpstr This is a whitespace sensitive, UTF-8, HTML string describing how to use the command.
- * The preferred format of this string shall be the commands name, followed by a space
- * and any arguments it accepts (if it takes any arguments, otherwise no space), followed
- * by a colon, two spaces, and a description of the command in sentence form. No slash
- * before the command name.
- * @param data User defined data to pass to the PurpleCmdFunc
- * @return A PurpleCmdId. This is only used for calling purple_cmd_unregister.
- * Returns 0 on failure.
