canlock-hfp [-d] [-n]

Header Field Parser (hfp) for RFC 8315 conformant header fields.

The header field is read from stdin.

The input data must be an unfolded "Cancel-Lock" or "Cancel-Key" header field without line break at the end. The utility canlock-mhp(1) can be used to extract the field from an article.

If such a header field is found, it is parsed according to the syntax defined in RFC 8315. If valid c-lock or c-key (respectively) elements are found, they are printed to stdout with SP (Space) as delimiter.

Note: Additional formatting output is printed on stderr to make the output more human readable on a terminal. Redirect stderr to /dev/null if this is not wanted.

The following options are supported:

Enable debug mode (messages are printed to stderr).
Print help message, then exit.
Prepend the data on stdout with the header field name (including the colon) and a SP (Space) delimiter.
Print version and compile time options, then exit.

Zero on success or regular exit respectively.
All other values indicate an error.
