GLIBC, also known as the GNU C Library, is a key component of the GNU Project that provides the core libraries for the GNU system and GNU/Linux systems. It is used as a complete implementation of the C library, which is defined by the ISO and ANSI C standards, plus many extensions.

Here are the steps to explain what GLIBC runtime is used for:

1. **C Library**: GLIBC is a C library, which is a collection of header files and pre-compiled libraries that can be used by C programs to perform specific tasks.

2. **System Calls**: GLIBC provides all of the necessary wrappers for system calls. System calls are requests made by running tasks for services from the computer's operating system.

3. **Standard Functions**: GLIBC provides all of the standard functions, like printf, malloc, scanf, etc., which are used in writing programs in C and C++.

4. **Mathematical Functions**: GLIBC provides mathematical libraries for complex mathematical operations.

5. **Thread Support**: GLIBC provides thread support, which is necessary for multitasking within a single application.

6. **Locale Support**: GLIBC provides locale support, which is necessary for internationalization and localization. This includes things like date and time formats, character classifications, and more.

In summary, GLIBC runtime is used to provide a system-level abstraction to help developers write applications more easily without having to worry about low-level details.
