Detailed Description

Thread-safe log manager with timestamps.

Provides synchronized logging to a file descriptor with automatic timestamp generation and optional debug information.

Thread Safety

All logging operations are protected by a mutex, making it safe for concurrent use from multiple threads.

Log Format

• Release: TIMESTAMP (thread_id:pid): MESSAGE
• Debug: TIMESTAMP (file:line:thread_id:pid): MESSAGE

Definition at line 91 of file log.H.
