SYNOPSIS

#define BSON_APPEND_REGEX(b, key, val, opt) \
   bson_append_regex (b, key, (int) strlen (key), val, opt)


bool
bson_append_regex (bson_t *bson,
                   const char *key,
                   int key_length,
                   const char *regex,
                   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.

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.
