Built-in Functions
Returns:
Function:
undefined
Copies n bytes from source to destination in RAM. Be aware that array names are
pointers where other variable names and structure names are not (and therefore
need a & before them).
Memmove performs a safe copy (overlapping objects doesn't cause a problem).
Copying takes place as if the n characters from the source are first copied into a
temporary array of n characters that doesn't overlap the destination and source
objects. Then the n characters from the temporary array are copied to destination.

memcpy(&structA, &structB, sizeof (structA));
memcpy(arrayA,arrayB,sizeof (arrayA));
memcpy(&structA, &databyte, 1);
char a[20]="hello";
memmove(a,a+2,5);

strcpy(), memset()
memset( )
Syntax:
memset ( destination , value , n )
Parameters: destination is a pointer to memory.
value is a 8 bit int
n is a 16 bit int.
On PCB and PCM parts n can only be 1-255.
Returns:
Function:
Availability:
undefined
Sets n number of bytes, starting at destination, to value. Be aware that array
names are pointers where other variable names and structure names are not (and
therefore need a & before them).
