Ring1_Memory_copySlow
Copy Bytes from a source memory block to a target memory block.
Ring1_Result
Ring1_Memory_copySlow
(
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.
This function handles copying between overlapping memory blocks However, its slower than Ring1_Memory_copyFast. If you can assert that the memory blocks are not overlapping, use the faster Ring1_Memory_copyFast.
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 value
This function returns 0 on success, a non-zero value on failure.
Post Conditions
If this function fails, then it sets the by-thread status variable.
Below is a list of failure conditions and the status codes indicating them.
Ring1_Status_InvalidArgument-
if
pand/orqisNULL
If this function fails, neither p nor p is not dereferenced.
