Usage

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.

Overview

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.
