58 * A callback invoked for output
60 * Passed arguments are:

62 * - string to append to the output
64 void (*dp_cb)(struct nl_dump_params *, char *);
67 * A callback invoked for every new line, can be used to
68 * customize the indentation.

71 * - dumping parameters
72 * - line number starting from 0
74 void (*dp_nl_cb)(struct nl_dump_params *, int);
77 * User data pointer, can be used to pass data to callbacks.
82 * File descriptor the dumping output should go to
87 * Alternatively the output may be redirected into a buffer
