Dear Sirs:
I am using FreeBSD-2.2.8 and after calling pthread_create()
my programs get sigfault (SIGSEGV) and exited with core dump.
I should like to ask if somebody know the solve of this problem.
My example of using pthread is included below.
I ask to answer me directly on my e-mail.
Oleg

saun.sun_family = AF_UNIX; strcpy(saun.sun_path, "/tmp/TS");
bind(lisfd, (struct sockaddr *) &saun, sizeof(struct sockaddr_un));
listen(lisfd, 2);
client = (struct sockaddr_un *)malloc(sizeof(saun));
confd = (int *)malloc(sizeof(int));
for ( ; ; ) {
len = sizeof(saun);
*confd = accept(lisfd, (struct sockaddr *) client, &len);
pthread_create(NULL, NULL, &coms, confd);
}
return(0);
