I seem to be having a memory leak when running a database of a memory card. The
emulator doesn't pick it up though. All is running fine if the database runs of
the device, but as soon as i run it of the memory card, it i start loosing
memory. I can't figure out what i'm doing wrong.. I'm closing the database once
finished with it. And since the emulator doesn't give me any memory leaks, i'm
assuming that all related memory has been cleared. As the memory loss doesn't
happen when running on the device, i assume it has to do with my VFS functions.
Is there something i'm missing?
I'm using the following code to open the database on the memory card...
FileRef theDatabaseFile;
static void OpenDatabaseVFS(Char *theDatabaseName)
{
UInt32 volumeIterator;
theDatabaseFile = NULL;
volumeIterator = vfsIteratorStart;
while ( (volumeIterator != vfsIteratorStop) &&
(VFSVolumeEnumerate (&volumeRefNum, &volumeIterator) ==
errNone) )
if ( (theDatabaseFile = FindFile (volumeRefNum, "/PALM/
Launcher",theDatabaseName)) != NULL )
volumeIterator = vfsIteratorStop;
else
{
if( StrCaselessCompare (theDatabaseName, databaseName) == 0)
{
//do something to display error can't find database
}
}
}
static FileRef FindFile (UInt16 volRefNum, Char *directory, Char
*theDatabaseName)
{
FileInfoType fileinfo;
FileRef dirRef, fileRef;
UInt32 dirIterator;
UInt16 length;
fileRef = NULL;
if ( VFSFileOpen (volRefNum, directory, vfsModeRead, &dirRef) ==
errNone )
{
StrCopy (pathname, directory);
if ( StrCompare (pathname, "/") != 0 )
StrCat (pathname, "/");
length = StrLen (pathname);
fileinfo.nameP = pathname + length;
fileinfo.nameBufLen = sizeof pathname - length;
dirIterator = vfsIteratorStart;
while ( (dirIterator != vfsIteratorStop) &&
(VFSDirEntryEnumerate (dirRef, &dirIterator, &fileinfo)
== errNone) )
{
if ( fileinfo.attributes & vfsFileAttrDirectory )
fileRef = FindFile (volRefNum, pathname, theDatabaseName);
else if ( StrCaselessCompare (fileinfo.nameP, theDatabaseName) == 0)
VFSFileOpen (volRefNum, pathname, vfsModeRead, &fileRef);
if ( fileRef != NULL )
dirIterator = vfsIteratorStop;
}
VFSFileClose (dirRef);
}
return fileRef;
}
And i just close the open fileRef with VFSFileClose.
Can anyone point me in the right direction
