Multithreaded File Manager with Synchronization

A multithreaded file manager designed to perform synchronized file operations across threads and processes. This application supports a variety of file operations, including read, write, copy, metadata retrieval, compression, and decompression, while ensuring thread and process safety using POSIX semaphores and read-write locks.

---

Features

• Multithreaded Operations
  Perform concurrent file operations using threads with proper synchronization via read-write locks.

• Process Synchronization
  Uses a named semaphore (/tmp/file_manager.lock) to ensure safe access across multiple processes.

• Interactive Content Input
  Supports multiline content input for write operations, with a maximum of 1024 characters per file.

• File Operations

  • Reading and writing files.
  • Retrieving file metadata (size, permissions, creation time).
  • Copying, deleting, and renaming files.
  • Compressing and decompressing files using zlib.

• Detailed Logging
  Logs all file operations in file_operations.log with timestamps for debugging and audit purposes.
