# bson\_errors(3)

Handling Errors

## NAME

bson\_errors - Handling Errors

## DESCRIPTION

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.
