Re: Unknown error code of VFSFileOpen

2004-03-31 Thread Jan Slodicka 
 Maybe the system doesn't know the error and give out memory error finally

Or there is some memory allocation behind each FileRef... File functions are
not published (most of the implementation must be on the driver level), so
it cannot be checked.

 After overnight checking the code line by line, the problem is due to
wrong
 statement:
 VFSFileClose( volRefNum );

 it should be VFSFileClose(fp);

 So bad that it doesn't give out any error during executing this command
for
 the first eight times. Maybe the system doesn't know the error and give
out
 memory error finally.

 Thanks all of you.

Sounds to me like you have a memory leak somewhere.

Decimal error 259 is memErrInvalidParam (invalid param or requested size 
is too big).
