SYNOPSIS

          #define BSON_APPEND_UNDEFINED(b, key) \
             bson_append_undefined (b, key, (int) strlen (key))

          bool
          bson_append_undefined (bson_t *bson, const char *key, int key_length);

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().

DESCRIPTION

       The  bson_append_undefined()  function  shall  append  a new element to bson of type BSON_TYPE_UNDEFINED.
       Undefined is common in Javascript. However, this element type is deprecated and should not be used in new
       code.

RETURNS

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