void dsub(unsigned char size,char *ptr1,char *ptr2,char *rst)
Description:
Header:
Parameters:
Example:
Subtracts size-byte data stored in the area starting from ptr2 from size-byte
data stored in the area starting from ptr1 in decimal and stores the result to
the size-byte area starting from rst. The size must be a constant from 1 to
255.
