Convert 3 (Man Page) to XML

The 3 file extension refers to Unix Section 3 manual pages, which document library functions in Unix-based systems. These manual pages, or man pages, provide detailed information about C library functions, excluding system call wrappers. Introduced as part of the Unix documentation system, they help users understand how to use various library functions effectively. You can view these files using the "man" utility or any text editor.

XML, or Extensible Markup Language, is a widely used file extension in computer technology. It is designed to store and transport data, enabling structured information exchange between different systems. XML files are both human- and machine-readable, making them versatile for various applications, including web services, configuration files, and data storage. Originating in the 1990s, XML was developed by the World Wide Web Consortium (W3C) to simplify data interchange and ensure platform independence. Its flexibility and extensibility have made it a standard in many IT environments, fostering seamless integration and data sharing across diverse platforms.
