If I have a variable, x, that will sometime be a normal printable string, and sometimes be some random hex data (including unprintable chars), how can I reliably print that will space padding? ex:
I have a buffer[] including HEX bytes and I want to search this bu开发者_如何学Goffer to find specific bytes. For example:
