An excerpt from PqAnywhere which does the same thing you are doing
(Part of ZBoxZ - OpenSource at palmboxer.sourceforge.net)
asz = 50;
ap = DmNewHandle(db, asz);
aiid = MemHandleToLocalID(ap);
xp = MemHandleLock(ap);
pqahead[13] = ( strlen(title) + 1 ) / 2;
strcpy(&pqahead[14],title);
DmWrite(xp, 0, pqahead, asz);
MemHandleUnlock(ap);
DmSetDatabaseInfo(0, lid, NULL, NULL, NULL, NULL, NULL, NULL,
NULL, &aiid, NULL, NULL, NULL);
Basically do the DmNewHandle call to allocate the memory, and
DmSetDatabaseInfo to attach it as the appinfo.
