bson_append_regex_w_len (bson_t *bson,


                          const char *key,


                          int key_length,


                          const char *regex,


                          int regex_length,


                          const char *options);

PARAMETERS

bson: A bson_t.
key: An ASCII C string containing the name of the field.
key_length: The length of key in bytes, or -1 to determine the length with strlen().
regex: An ASCII string containing the regex.

options: An optional string containing the regex options as a string.
