Detailed Description

template<class T, int(allocator)(T **), void(deleter)(T *)>
class AlsaMallocWrapper< T,, >

Wrapper for avoiding use of the ALSA alloca based functions which do not work well with -fstack-protector of newer GCC versions, and also avoids potential memory leaks when using pure ALSA malloc/free based functions.
