Try this in mycmd: u8 * line; if (unformat (input, "%U", unformat_line, &line)) process_line;
Note that line will be a true u8 * vector: no null-termination. If you need null termination: vec_add1 (line, 0); Remember to vec_free(...) it unless you're planning to keep it. HTH...

My requirement is that if my command is "mycmd" followed by some string (which may have spaces in it), then I should be able to read the entire string up to the \n character typed by the user. Eg. if the command is typed like mycmd foo1 foo2 foo3 (the "path" of the VLIB_CLI_COMMAND is "mycmd") Then in my CLI callback function, I want to be able to get the string "foo1 foo2 foo3" setup in a u8* variable. If the leading and trailing spaces are trimmed, I am fine by that. I am looking for the correct way to call the unformat functions in my command callback function to achieve this. Regards -Prashant
