Re: [Boost-Users] detail/lightweight_mutex.hpp

From: "Tom Matelich"

I'm attempting to go to Boost 1.28 on our HPUX 10.20 boxes. I've run into a problem with an assumption about the type of pthread_mutexattr_t. detail\lwm_pthreads.hpp calls:

pthread_mutex_init(&m_, 0);

HP's pthread.h (10.20 uses DCE) has that defined as:

int pthread_mutex_init (pthread_mutex_t *,pthread_mutexattr_t);

I don't know what to do about it. My POSIX draft says int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); and goes on to specify that 0/NULL for the second argument causes default attributes to be used. I know little - if anything - about HPUX 10.20; if you find a solution let me know, and I'll incorporate it into lwm_pthreads.hpp. Sorry.
