git - c - standard file descriptor - open if missing -

git - c - standard file descriptor - open if missing - i saw next function in setup.c of git source code. code: /* if standard file descriptor missing open /dev/null */ void sanitize_stdfds(void) { int fd = open("/dev/null", o_rdwr, 0); while (fd != -1 && fd < 2) fd = dup(fd); if (fd == -1) die_errno("open /dev/null or dup failed"); if (fd > 2) close(fd); } it seek open stdio file descriptors (0/1/2) /dev/null, if missing. my question is: in while (fd != -1 && fd < 2) , why utilize 2, not 3. because if fd == 2 have opened file descriptors 0,1,2 , there nil more do. needed open 3 descriptors stdin, stdout , stderr. if set there 3, loop open file descriptors 0,1,2,3. line if (fd > 2) close(fd); close descriptor 3. work in both cases, original solution better. c git stdio
