Handling Errors


Many libbson functions report errors by returning NULL or -1 and filling out a bson_error_t structure with an error domain, error code, and message.

  • error.domain names the subsystem that generated the error.
  • error.code is a domain-specific error type.
  • error.message describes the error.

Some error codes overlap with others; always check both the domain and code to determine the type of error.
