NAME

       bson_append_regex - bson_append_regex()

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.
