Fair enough then. Obviously the non-LFS 32-bit variation has to sign-extend the offset as this is how the off_t type has been defined in this case, though it is interesting to note that the kernel treats this argument as unsigned while the C library API defines it as signed and there is no range checking in between. Hmm... Maciej
