folly::getBaseLoggingConfig

Declared in <folly/logging/Init.h>

You can define this function in your executable and folly::initLogging() will call it to get the base logging configuration. The settings returned by getBaseLoggingConfig() will then be modified by updating them with the configuration string parameter passed to initLogging().

This allows the user‐specified configuration passed to initLogging() to update the base configuration. The user‐specified configuration can apply additional settings, and it may also override settings for categories and handlers defined in the base configuration.

See folly/logging/example/main.cpp for an example that defines getBaseLoggingConfig().

If this function returns a non‐null pointer, it should point to a null‐terminated string with static storage duration.

The base logging configuration string, or null for none.
