This function is Hardware-specific implementation. It is not implemented in this Compiler.
#include <stdlib.h>
void *calloc(size_t n, size_t size);
calloc() allocates a block of memory for an array containing n elements of size size, and initializes all bytes in the memory block to zero. To deallocate the block, use free(). Do not use the default implementation in interrupt routines as it is not reentrant.
calloc() returns a pointer to the allocated memory block. If calloc() cannot allocate the block, the return value is NULL.
