I'm using VFSFileDBInfo() to get prc/pdb info about files on an external card. Here's
the call:
err = VFSFileDBInfo( fileRefP, dbName, &attributes, &version, &crDate, &modDate,
&bckUpDate, &modNum, 0, 0, &type, &creator, &numRecords );
if( err == errNone )
{
// do my stuff here
}
But, this API causes the following error with some files:
"SystemCompatibility.c, Line:642, Null handle"
It looks like you get this error if you call VFSFileDBInfo() on a file that is not a
.prc or .pdb file. (it would be nice if it returned an error instead).
My problem is that even if I put in a check to make sure that the filename ends in
.prc or .pdb, I still get the error on some files.
Is there any way to check a file to make sure that VFSFileDBInfo() won't crash the OS
when you call it?
Also, does anyone know what line 642 of SystemCompatibility.c does?
Thanks!
