Hi all!
When changing cthread code to pthread i have found this problem:
In file hurd/libpipe/pipe.c appear the following functions:
condition_implies and condition_unimplies
What are the best way to change them to pthread?
form cprocs.c and libpthread/sysdeps/generic/bits/condition.h ... files:
condition_implies (condition_t implicator, condition_t implicatand)
{
struct cond_imp *imp;
imp = malloc (sizeof (struct cond_imp));
imp->implicatand = implicatand;
imp->next = implicator->implications;
implicator->implications = imp;
}
typedef struct condition {
spin_lock_t lock;
struct cthread_queue queue;
const char *name;
struct cond_imp *implications;
} *condition_t;
struct __pthread_cond
{
__pthread_spinlock_t __lock;
struct __pthread *__queue;
struct __pthread_condattr *__attr;
struct __pthread_condimpl *__impl;
void *__data;
};
I use hurd-20021118 debian source package.
struct condition and __pthread_cond look similar. Coding a
condition_implies replacement with __pthread_condimpl instead cond_imp
seems easy, but i dont find __pthread_condimpl definition anywhere.
Can anyone enlight me on that?
Thanks,
Vicente.
