magic functions check whether the pointer is valid, i.e. really allocated via snd_magic_kmalloc(). it's good for a void pointer, which type can not be known at the compile time. please note that the buffer allocated via snd_magic_kmalloc must be released via snd_magic_kfree(), not usual kfree(). > What is actual status of kernel API documentation.
