xRead abstract method
Fill the target
with bytes read from fileOffset
.
If the file is not large enough to fullfill the read, a VfsException
with an error code of SqlExtendedError.SQLITE_IOERR_SHORT_READ must be
thrown. Additional, the rest of target
must be filled with zeroes.
Safety warning: Target may be a direct view over native memory that must not be used after this function returns.
Implementation
void xRead(Uint8List target, int fileOffset);
