Re: [alsa-devel] portability: types

The next big issue is that multiple places include Linux specific header files, easily recognizable by the path linux/*.h.

Once upon a time, alsa-lib was used only on Linux (and also on old versions such as 2.2.x).

I think these are used to define unusual types like __u32, __u64, __kernel_off_t, __kernel_pid_t. There are also a number of cases of u_xxx_t (which don't exist on Solaris) vs. the uxxx_t defined in C99.

Many of these types have POSIX equivalents, like uint32_t, uint64_t, off_t, pid_t.

Would it be better to switch to those, or should we define compat #typedefs or #defines in local.h?

Linux-specific types should be used only in code that actually is Linux specific (i.e., the xxx_hw plugins).
