stderr_output

Writes to the C standard error stream.

Description

If an output policy is present, the default error handler uses it to write error messages to its output stream. registry::initialize can also use it to write trace messages.

Requirements

Classes implementing this policy must:

  • derive from `output`.

  • provide a `fn<Registry>` metafunction that conforms to the OutputFn blueprint.
