Runtime libraries

Atollic TrueSTUDIO® includes a number of runtime and math libraries for C and C++:

• C runtime library
• C math library
• C++ runtime library

The C runtime library can optionally be remapped to the underlying platform, such that function calls like printf() is remapped to devices like UART channels or LCD displays, fopen() and flose() is remapped to API calls to an RTOS or flash file system, etc.

The libraries are instrumented with linker optimization information, that enables the optimizing linker to remove library functions not used by the application, thus reducing the memory overhead for small embedded systems.
