Source position: exec.pas line 1313
procedure CopyMemQuick( |
const Source: APTR; |
Dest: APTR; |
Size: ULONG |
); |
Source |
|
A long aligned pointer to the begin of source data |
Dest |
|
A long aligned pointer to begin of destination memory block |
Size |
|
Number of bytes to be copied from source to destination, 0 is allowed and do nothing |
CopyMemQuick is a highly optimized memory copy function, with restrictions on the size and alignment of its arguments. Both the source and destination pointers must be longword aligned. In addition, the size must be an integral number of longwords (e.g. the size must be evenly divisible by four).
Arbitrary overlapping copies are not supported.
