hej!
got to the upper limits of size :)) time to be more dynamic..
this is a normal section of standard C code for allocating
a 10x10 array of characters.
---
{
char **myStrings;
int i, count;
// allocate the memory
count = 10;
myStrings = (char **)malloc(count * sizeof(char *));
for (i=0; i<count; i++) {
myStrings[i] = (char *)malloc(10 * sizeof(char));
sprintf(myStrings[i], "%d", count);
}
// do something
...
// free the memory
for (i=0; i<count; i++) {
free(myStrings[i]);
}
free(myStrings);
}
---
a direct port to the palmOS i thought would be like
this:
---
{
CharPtr *myStrings;
int i, count;
// allocate the memory
count = 10;
myStrings = (CharPtr *)MemPtrNew(count * sizeof(CharPtr));
for (i=0; i<count; i++) {
myStrings[i] = (char *)MemPtrNew(10 * sizeof(Char));
StrIToA(myStrings[i], count);
}
// do something (like set the values in a pull down list)
LstSetListChoices(listP, myStrings, count);
// free the memory
for (i=0; i<count; i++) {
MemPtrFree(myStrings[i]);
}
MemPtrFree(myStrings);
}
---
but this gives me unallocated memory errors..
any pointers? should i be allocating memory to
handles and then lock those handles to pointer
references?
the API says the following for MemPtrNew:
---
Allocate a new nonmovable chunk in the dynamic heap.
---
does my code "move" the chunk of memory? :)
cheers.
az.
