I'm having trouble with my first attempt to read off an Application Info
Block from a database [a short list of strings created by a conduit].
Everything seems to run fine, but when execution goes into a following
method, the execution bombs out on an attempt to call MemPtrNew.
I've included a pruned down copy of the code I use in the method. I'm
unlocking the pointer I got from MemLocalIDToLockedPtr - am I perhaps meant
to use some method to release the LocalIDs that get returned, as well?
Thanks for any help.
void static LoadDbAppInfo(FormPtr frmP, DmOpenRef dbP)
{
LocalID dbID, appInfoIDP;
unsigned short cardNo;
int catCtr;
char *p;
dbID = NULL; appInfoIDP = NULL;
if (dbP == NULL) goto FillOutList;
if (DmOpenDatabaseInfo(dbP, &dbID, NULL, NULL, &cardNo, NULL)) goto
FillOutList;
if (DmDatabaseInfo(0, dbID, NULL, NULL, NULL, NULL, NULL, NULL, NULL,
&appInfoIDP, NULL, NULL, NULL)) goto FillOutList;
if (!appInfoIDP) goto FillOutList;
p = (char *) MemLocalIDToLockedPtr(appInfoIDP, cardNo);
FillOutList:
...Here I process the data block, or do some default handling if there was
none ...
// Release the resources
if (p) MemPtrUnlock(catListP);
}
