Although these functions are not in POSIX, they are widely used on *nixes and the part proposal the next POSIX. My question what is the best equivalent for the opentat() functions that can be used in multithreaded application. Currently I use something like this: int openat(int dirfd, const char *pathname, int flags, ...) { int fd; if(fchdir(dirfd) < 0) { perror("fchdir"); return -1; } fd = open(pathname, flags, mode); // chdir to the original CWD return fd; } But this is not a perfect solution - current working directory is shared among all threads, it means that openat() may affect other threads. Is there an equivalent of this implementation without changing the current directory? _______________________________________________ Do not post admin requests to the list. They will be ignored.
