typedef u16_t mem_size_t |
void * mem_calloc | ( | mem_size_t | count, |
mem_size_t | size | ||
) |
Contiguously allocates enough space for count objects that are size bytes of memory each and returns a pointer to the allocated memory.
The allocated memory is filled with bytes of value zero.
count | number of objects to allocate |
size | size of the objects to allocate |

void * mem_malloc | ( | mem_size_t | size_in | ) |
Allocate a block of memory with a minimum of 'size' bytes.
size_in | is the minimum size of the requested block in bytes. |
Note that the returned value will always be aligned (as defined by MEM_ALIGNMENT).

void * mem_trim | ( | void * | rmem, |
mem_size_t | new_size | ||
) |
Shrink memory returned by mem_malloc().
rmem | pointer to memory allocated by mem_malloc the is to be shrunk |
new_size | required size after shrinking (needs to be smaller than or equal to the previous size) |
