我一直在墙上敲打几个小时,现在试图找出造成这一段错误的原因.
我发现segfault pthread_mutex_lock(lock)在线上一致地发生(38).我已经在锁定周围放置了两个打印语句,但是只有其中一个打印,这是我得出结论在该指令处发生段错误的理由.
我使用互斥正确锁紧,还是我做我的阵列错误(buffer[]和numbermarker[]？
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
int* numbermarker = NULL;
int* buffer = NULL;
int pullposition = 0;
int placeposition = 1;
pthread_mutex_t *lock;
int ceiling;
/*This method places one of the primes in the buffer. It
offers a safe way to manage where the next value will be placed*/
void placevalue(int value)
{
buffer[placeposition] = value;
placeposition++;
}
/*This method pulls the next prime and increments to the next prime …
