I try read data from my binary file:

iFileConnection = (FileConnection) Connector.open(aPath, Connector.READ);
 iDataInputStream = iFileConnection.openDataInputStream();

//read some data
....

iDataInputStream.mark(1);

//read some data
....

// try return to mark position
// THIS WORK FINE ON S40 BUT NOT WORK ON S60 (position not change) !!! WHY ???

iDataInputStream.reset();

I don't understand why that not work on S60 (return to mark position) ?
Please help me.

InputStream.mark() and InputStream.reset() are optional. Check the return value from markSupported() to see if the InputStream you're using supports marking.

If markSupported() returns false, then, no, this is not a bug.

markSupported() return TRUE !!!

Why "1"? As soon as one byte is read, the marked position may become invalid. Try using a higher value (larger than the number of bytes you want to read past the mark).
