NAME

       bson_append_regex_w_len - bson_append_regex_w_len()

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 key in bytes, or -1 to determine the length with strlen().

       • regex: An ASCII string containing the regex.

       • regex_length: The length of regex in bytes, or -1 to determine the length with strlen().

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

DESCRIPTION

       Appends  a  new  field  to bson of type BSON_TYPE_REGEX. regex should be the regex string.
       options should contain the options for the regex.

       Valid characters for options include:

       • 'i' for case-insensitive.

       • 'm' for multiple matching.

       • 'x' for verbose mode.

       • 'l' to make w and W locale dependent.

       • 's' for dotall mode ('.' matches everything)

       • 'u' to make w and W match unicode.

RETURNS

       Returns true if the  operation  was  applied  successfully.  The  function  will  fail  if
       appending the regex grows bson larger than INT32_MAX.
