Ok, so what I have now is:
Boolean SARaddSegment(Int32 pos, Boolean last, char *data, UInt32 size, int
type, GlobalsType *g)
{
SARPtr tmp, sar;
Int32 j = 0;
sar = g->segment;
while(sar != NULL)
{
if (pos == sar->pos)
{
return(false); // We already added this segment, I
hope...
}
sar = sar->next;
}
tmp = Malloc(sizeof(SARType));
MemSet(tmp,sizeof(SARType),0);
ErrFatalDisplayIf (!tmp, "Malloc Failed");
tmp->pos = pos;
tmp->last = last;
if (type == 2)
tmp->size = size-4;
else
tmp->size = size;
tmp->data = Malloc(tmp->size+1);
ErrFatalDisplayIf (!tmp->data, "Malloc Failed");
if (type == 2) {
for (j=0; j<(tmp->size);j++)
tmp->data[j] = data[j+4];
} else {
for (j=0; j<(tmp->size);j++)
tmp->data[j] = data[j];
}
tmp->next = g->segment;
g->segment = tmp;
return(true);
}
Boolean SARreassemble(char *buf, Int16 buflen, GlobalsType *g)
{
SARPtr tmp;
Int32 o = 0, j = 0;
UInt32 offset = 0;
Boolean finished = false;
Int32 lastpkt = 0;
tmp = g->segment;
while (tmp != NULL) {
if (tmp->last) {
lastpkt = tmp->pos;
break;
}
tmp = tmp->next;
}
tmp = g->segment;
while(!finished)
{
while(tmp != NULL){
if (tmp->pos == o)
break;
else
tmp = tmp->next;
}
if (MemPtrSize(buf) < (offset+tmp->size+1))
MemPtrResize(buf, offset+tmp->size+1);
for (j=0; j<(tmp->size);j++)
buf[j+offset] = tmp->data[j];
offset += tmp->size;
if (o == lastpkt)
finished = true;
o++; // increase offeset
tmp = g->segment; // start over
}
return true;
}
The data is being copied (no fatal errors), but the problem I am having is that
some of the data is either not being copied to the final buffer in
SARreassemble, or that the data is corrupt. Unfortunatly I do not have an
example of the data that is being corrupted at the moment.
Basically WAP packets are sent over UDP/IP (WDP), and they are sent as a bunch
of octets representing the data.
I.e. the WSP equivilant of the HTTP GET header is 0x04, saving two bytes in a
message.
Thanks,
Donald
