@micro-os-plus/c-libs

µOS++ complementary C library functions

These are some files that complement or extend the C library:

- c-syscalls-empty.c define weak empty syscalls to keep the linker happy; redefine those needed for retargeted configurations;
- _sbrk.c allocates block of memory in the free store (the heap) at the end of RAM, up to the stack; must match the definitons in the linker script;
- stdlib/assert.c defines the function to be called when assertions are taken;
- stdlib/atexit.cpp defines a simple registry for functions to be called when the program is terminated; useful for semihosting applications that terminate normally; the size of the static array is OS_INTEGER_ATEXIT_ARRAY_SIZE, default 3;
- stdlib/exit.c defines the functionality of exit() and abort()
- stdlib/init-fini.c defines weak empty _init() and _fini(), to keep linker happy.
