Function Documentation

◆ qt_initial_random_value()

QRandomGenerator::InitialRandomData qt_initial_random_value ( )

noexcept

Returns an initial random value (useful for QHash's global seed). This function attempts to use OS-provided random values to avoid initializing QRandomGenerator::system() and qsimd.cpp.

Note: on some systems, this functionn may rerturn the same value every time it is called.
