42 * An optional interface for tools to specify what options they support.
43 * They are concatenated with main's options and passed to getopt_long.
45 * The callee can choose to set *opts to a tpm_options pointer allocated
46 * via tpm2_options_new(). Setting *opts to NULL is not an error, and
47 * Indicates that no options are specified by the tool.
50 * True on success, false on error.

58 * The system api context.
60 * Flags that tools may wish to respect.

67 * Called when the tool is exiting, useful for cleanup.

72 * prints output to stdout respecting the quiet option.
73 * Ie when quiet, don't print.
75 * The format specifier, ala printf.
77 * The varargs, just like printf.
