The CACE library provides a general purpose thread-safe logging facility for the library itself and users of the library.

Logging must be initialized once per process using cace_openlog() and should be de-initialized before exiting the process using cace_closelog(). Log events themselves are queued by using one of the severity-specific macros listed below.

The supported log severity values are a subset of the POSIX syslog values with enumerations and descriptions repeated below.

LOG_CRIT critical conditions, logged by CACE_LOG_CRIT
LOG_ERR error conditions, logged by CACE_LOG_ERR
LOG_WARNING warning conditions, logged by CACE_LOG_WARNING
LOG_INFO informational message, logged by CACE_LOG_INFO
LOG_DEBUG debug-level message, logged by CACE_LOG_DEBUG
