Synopsis¶
bool
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- keyin bytes, or -1 to determine the length with- strlen().
- regex: An ASCII string containing the regex.
- regex_length: The length of- regexin bytes, or -1 to determine the length with- strlen().
- options: An optional string containing the regex options as a string.
