Ring1_Memory_copyFast
(
void *p,
const void *q,
size_t n
)
This function copies
n
Bytes from a source memory block pointed to by
q
to a target memory block pointed to by
p.
The memory blocks must not overlap or the behavior of this function is undefined. Use Ring1_Memory_copySlow to copy Bytes between overlapping memory blocks.
Parameter variables
p- A pointer to the target memory block.
q- A pointer to the source memory block.
n- The number of Bytes to copy.
Return Values
Ring1_Result_Success on success, Ring1_Result_Failure on failure.
