... and when using gthr-mipssde.h / gthr-posix95.h / gthr-solaris.h:
static inline int
__recursive_mutex_destroy(__gthread_recursive_mutex_t* __rmutex)
{
return ___gthread_mutex_destroy(__mutex->actual);
}
Adding the right preprocessor checks to the library will be messy, because
configure might have made gthr-default.h a symlink to one of the headers above
and we don't have a macro to test. The right place for the destroy function is
in the gthr headers where __gthread_recursive_mutex_t is defined.
Hmm, I wonder if we could use sfinae, there are three cases:
- recursive mutex is the same type as the non-recursive mutex, or
- it has an "actual" member, or
- it has a "sema" member.
I'll try that this evening.
