I have a file locking problem that is solved under Mac and Linux using fcntl: int lockRepFile (int fd, char lock, size_t from, size_t length) { struct flock fl; fl.l_start = from; fl.l_len = length; fl.l_pid = 0; if (lock == 'r') fl.l_type = F_RDLCK; else if (lock == 'w') fl.l_type = F_WRLCK; else if (lock == 'u') fl.l_type = F_UNLCK; fl.l_whence = SEEK_SET; return (fcntl(fd, F_SETLKW, &fl)); } Now, unfortunately this hangs occasionally using cygwin - gcc. I would appreciate any comments and suggestions on how debug this and how to improve the performance i.e. stop it from hanging...
