Detailed Description

A means to serialize access to a resource between threads.

Mutexes (short for "mutual exclusion") are a synchronization primitive that allows exactly one thread to proceed at a time.

Wikipedia has a thorough explanation of the concept:

Since

This struct is available since SDL 3.2.0.

Category:

Resource

Constructor & Destructor Documentation

Mutex()

SDL::Mutex::Mutex ( MutexRaw resource )

inlineexplicitconstexprnoexcept

Constructs from raw Mutex.

Parameters

resource

a MutexRaw to be wrapped.

This assumes the ownership, call release() if you need to take back.
