UnPacked data:
--------------
typedef struct
{
Char first[15];
Char last[15];
} myRecord;
example:
myRecord r;
StrCopy(r.first, "Joe");
StrCopy(r.last, "Baloney");
the result is
Joe0***********Baloney0*******
(where * represents any char, 0 represents '\0')
Packed data:
------------
typedef struct
{
Char *firstlast;
} myPackedRecord;
example:
myPackedRecord pr;
pr.firstlast = MemPtrNew(12);
MemMove(pr.firstlast, "Joe", 4);
MemMove(pr.firstlast+4,"Baloney", 8);
the result is
Joe0Baloney0
The packed data takes up less space on your handheld. But, before your
program can use it, the data must be unpacked -- separated into the two
strings, first and last.
(Apoligies in advance if there are any typos in the above, untested,
code.)
