+Retrieves compile-time enabled backends.
+
+
+Parameters
+----------
+pBackends(out, optional)
+    A pointer to the buffer that will receive the enabled backends. Set to NULL to retrieve the backend count. Setting
+    the capacity of the buffer to `MA_BUFFER_COUNT` will guarantee it's large enough for all backends.
+
+backendCap(in)
+    The capacity of the `pBackends` buffer.
+
+pBackendCount(out)
+    A pointer to the variable that will receive the enabled backend count.
+
+
+Return Value
+------------
+MA_SUCCESS if successful.
+MA_INVALID_ARGS if `pBackendCount` is NULL.
+MA_NO_SPACE if the capacity of `pBackends` is not large enough.
+
+If `MA_NO_SPACE` is returned, the `pBackends` buffer will be filled with `*pBackendCount` values.
+
+
+Thread Safety
+-------------
+Safe.
+
+
+Callback Safety
+---------------
+Safe.
+
+
+Remarks
+-------
+If you want to retrieve the number of backends so you can determine the capacity of `pBackends` buffer, you can call
+this function with `pBackends` set to NULL.
+
+This will also enumerate the null backend. If you don't want to include this you need to check for `ma_backend_null`
+when you enumerate over the returned backends and handle it appropriately. Alternatively, you can disable it at
+compile time with `MA_NO_NULL`.
+
+The returned backends are determined based on compile time settings, not the platform it's currently running on. For
+example, PulseAudio will be returned if it was enabled at compile time, even when the user doesn't actually have
+PulseAudio installed.
+
+
+Example 1
+---------
+The example below retrieves the enabled backend count using a fixed sized buffer allocated on the stack. The buffer is
+given a capacity of `MA_BACKEND_COUNT` which will guarantee it'll be large enough to store all available backends.
+Since `MA_BACKEND_COUNT` is always a relatively small value, this should be suitable for most scenarios.
+
+```
+ma_backend enabledBackends[MA_BACKEND_COUNT];
+size_t enabledBackendCount;
+
+result = ma_get_enabled_backends(enabledBackends, MA_BACKEND_COUNT, &enabledBackendCount);
+if (result != MA_SUCCESS) {
+    // Failed to retrieve enabled backends. Should never happen in this example since all inputs are valid.
+}
+```
