Great! Indeed, this is better, will produce another iteration.#if defined(_GLIBCPP_HAVE_S_ISREG) || defined(_GLIBCPP_HAVE_S_IFREG) # ifdef _GLIBCPP_HAVE_S_ISREG # #define _GLIBCPP_ISREG(x) S_ISREG(x) # else # #define _GLIBCPP_ISREG(x) (S_IFREG & (x)) # endif // Regular files. struct stat __buffer; int __ret = fstat(this->fd(), &__buffer); if (!__ret && _GLIBCPP_ISREG(__buffer.st_mode)) if (__stdio) return __buffer.st_size - ftell(_M_cfile); else return __buffer.st_size - lseek(this->fd(), 0, ios_base::cur); #endif return 0; }
Good (*).About ioctl, I haven't been able to find an example of a modernIt works on all the platforms I care about anyway.
system having it in <ioctl.h>, not in <sys/ioctl.h> or <sys/filio.h>,
therefore I'm relying on the code which I stolen from libjava:
seems to work well there for a variety of different platforms.
