From 4d9c4025222e19dac9a90cabe8bd886e47959ad6 Mon Sep 17 00:00:00 2001 From: Sander Vrijders Date: Thu, 17 Aug 2017 16:56:00 +0200 Subject: lib: Add basic FRCT mechanisms This adds the basic FRCT mechanisms to the library. Upon flow alloc or accept an FRCT instance is now created and used when reading or writing to the flow. The timerwheel has been refactored to allow recharging timers and removing them and is now part of the library. The first SDU sent over the connection has the DRF set and this initializes the connection. Sender and receiver inactivity timers are added. --- src/lib/shm_rbuff_pthr.c | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) (limited to 'src/lib/shm_rbuff_pthr.c') diff --git a/src/lib/shm_rbuff_pthr.c b/src/lib/shm_rbuff_pthr.c index 44001458..7dc5f5d9 100644 --- a/src/lib/shm_rbuff_pthr.c +++ b/src/lib/shm_rbuff_pthr.c @@ -284,18 +284,12 @@ ssize_t shm_rbuff_read(struct shm_rbuff * rb) } ssize_t shm_rbuff_read_b(struct shm_rbuff * rb, - const struct timespec * timeout) + const struct timespec * abstime) { - struct timespec abstime; ssize_t idx = -1; assert(rb); - if (timeout != NULL) { - clock_gettime(PTHREAD_COND_CLOCK, &abstime); - ts_add(&abstime, timeout, &abstime); - } - #ifndef HAVE_ROBUST_MUTEX pthread_mutex_lock(rb->lock); #else @@ -306,10 +300,10 @@ ssize_t shm_rbuff_read_b(struct shm_rbuff * rb, (void *) rb->lock); while (shm_rbuff_empty(rb) && (idx != -ETIMEDOUT)) { - if (timeout != NULL) + if (abstime != NULL) idx = -pthread_cond_timedwait(rb->add, rb->lock, - &abstime); + abstime); else idx = -pthread_cond_wait(rb->add, rb->lock); #ifdef HAVE_ROBUST_MUTEX -- cgit v1.2.3
