◆ OtaFree_t

typedef void(* OtaFree_t) (void *ptr)

Free memory.

This function deallocates the memory previously allocated by a call to allocation function of type OtaMalloc_t.

Parameters
[ptr]This is the pointer to a memory block previously allocated with function of type OtaMalloc_t. If a null pointer is passed as argument, no action occurs.
Returns
None.
