The following runtime libraries are provided to support compiled C and C++:
- C standardlib
C library consisting of:
Functions defined by the ISO C library standard.
Target‑dependent functions used to implement the C library functions in the semihosted execution environment. You can redefine these functions in your own application.
Helper functions used to compile in C and C++.
- C microlib
C micro-library (microlib) consisting of:
Functions that are highly optimized to achieve the minimum code size.
Functions that are not compliant with ISO C library standard.
Functions that are not compliant with IEEE 754 standard for binary floating point arithmetic.
- C++
C++ library containing the functions defined by the ISO C++ library standard.
The C++ libraries depend on the C library for target‑specific support. There are no target dependencies in the C++ libraries.
The C++ libraries consist of:
the Rogue Wave Standard C++ Library
helper functions when compiling C++
additional C++ functions not supported by the Rogue Wave library.
