&file instead of fileP. You have to provide space for the FilePointer.
If Christiano Weirich use the wrong type declaration
for VFSFileOpen() (4th parameter FileRef; 'call by value' instead of 
'call by reference'), he will obtain an error at compile time.

But he compile and get a 'sysErrParamErr' at runtime.
Without seeing all additional parameters (and declarations), i guess 
volRefNum is wrong.

Please use ONLY volRefNum numbers recieved within the 
VFSVolumeEnumerate() os call

-- 8< -- example code ------- 8< --- start
Err     err;
UInt32  volIterator;
UInt16  volRefNum;
FileRef fileRef;
fileRef = vfsInvalidFileRef;
volIterator = vfsIteratorStart;
error = VFSVolumeEnumerate(&volRefNum, &volIterator);
if (error==errNone)
{
        error = VFSFileOpen(volRefNum, pathName, vfsModeRead, &fileRef);
}
-- 8< -- example code ------- 8< --- end
Use also only the full path to a file, e.g. /PALM/Launcher/prfbkp.txt
kindly regards,
