From: mookid@sigent.ru (Mikhail Zabaluev) To: devel@linux.iplabs.ru Subject: [devel] 64-bit fcntl Date: Mon, 16 Oct 2000 09:52:46 +0400 Message-ID: <20001016095246.A871@localhost.localdomain> (raw) [-- Attachment #1: Type: text/plain, Size: 511 bytes --] Доброе время суток. Почему fcntl в режиме поддержки 64-битных файловых смещений не хочет выполнять операцию F_SETLKW (она же F_SETLKW64)? Версия glibc - 2.1.95, ядра - 2.2.17. Текст тестовой программы приложен. Интересно, что strace как будто ничего не знает о константе F_SETLKW64: fcntl(4, 0xe /* F_??? */, 0xbffff800) = -1 EINVAL (Invalid argument) -- Stay tuned, MhZ mailto:mookid@sigent.ru ----------- "If value corrupts then absolute value corrupts absolutely." [-- Attachment #2: fcntl-test.c --] [-- Type: text/plain, Size: 390 bytes --] #define _FILE_OFFSET_BITS 64 #include <fcntl.h> #include <stdio.h> static struct flock lock = { F_WRLCK, SEEK_CUR, 0, 0, 0 }; int main() { int fd; fd = open("dummy_lockfile", O_WRONLY | O_CREAT, 0644); if (fd < 0) { perror("Cannot open dummy_lockfile"); return 1; } if (fcntl(fd, F_SETLKW, &lock) < 0) { perror("F_SETLKW failed"); return 2; } return 0; }
