Function config_log

pub unsafe fn config_log(callback: Option<fn(c_int, &str)>) -> Result<()>

Available on crate feature trace only.

Set up the process-wide SQLite error logging callback.

Safety

This function is marked unsafe for two reasons:

• The function is not threadsafe. No other SQLite calls may be made while config_log is running, and multiple threads may not call config_log simultaneously.
• The provided callback itself function has two requirements:
  • It must not invoke any SQLite calls.
  • It must be threadsafe if SQLite is used in a multithreaded way.
