// # AutoMemMap
|
|
//
|
|
// AutoMemMap is an RAII class to manage mapping a file to memory. It is a
|
|
// wrapper aorund managing opening and closing a file and calling PR_MemMap and
|
|
// PR_MemUnmap.
|
|
//
|
|
// Example usage:
|
|
//
|
|
// {
|
|
// AutoMemMap mm;
|
|
// if (NS_FAILED(mm.init("/path/to/desired/file"))) {
|
|
// // Handle the error however you see fit.
|
|
// return false;
|
|
// }
|
|
//
|
|
// doStuffWithMappedMemory(mm.address());
|
|
// }
|
|
// // The memory is automatically unmapped when the AutoMemMap leaves scope.
