Well for the aligned pointer allocation you can use posix_memalign
which from the Linux man page looks like:

       #define _XOPEN_SOURCE 600
       #include <stdlib.h>

       int posix_memalign(void **memptr, size_t alignment, size_t size);

       The function posix_memalign() allocates size bytes and places 
       the address of the allocated memory in *memptr.  The address of 
       the allocated memory will be a multiple  of  alignment, which 
       must be a power of two and a multiple of sizeof(void *).
