This function deallocates a specified memory segment (ptr). If the memory segment
was not previously allocated by calloc(), malloc() or realloc(), or if the space
has been deallocated by a call to free() or realloc(), the results are
unpredictable.
ptr Points to the memory segment to deallocate.
This function does not return a value. If an error occurs, errno is set.
Refer to Appendix B.
