Detailed Description

\inmodule QtCore

A class which holds a native socket descriptor.

Since

5.15

QSocketDescriptor makes it easier to handle native socket descriptors in cross-platform code.

On Windows it holds a {Qt::HANDLE} and on Unix it holds an int. The class will implicitly convert between the class and the native descriptor type.
