Hi,
Are there any issues that i should now about memcpy and multithreading in FreeBSD?
I've got a code which reads:
memcpy(&(h.req), req, sizeof(struct request));
and I keep getting SIGSEGV there in FreeBSD but not in Linux.
PS: Of course, I protect the write operation with a mutex.
PS2:
typedef struct hist_data {
struct request req;
int nthreads;
int bwritten;
struct thread_data wthread[MAXTHREADS];
} hist_data;
