This is only true for standard non-threaded library. Threaded library calls do not change errno. >How-To-Repeat: Try the following: 1. with standard, non-threada libc 2. with threaded library (libc_r) 3. change printf -> fprintf(stdout), then to fprintf(stderr). #include <sys/errno.h> #include <stdio.h> void main(void) { printf("errno=%d\n", errno); printf("errno=%d\n", errno); } >Fix: Sorry, not available yet. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
