NAMEfstatat - get file status relative to a directory file descriptor
#include <fcntl.h> /* Definition of AT_* constants */ #include <sys/stat.h> int fstatat(int dirfd, const char *pathname, struct stat *buf, int flags);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThe fstatat() system call operates in exactly the same way as stat(2), except for the differences described in this manual page.
If the pathname given in pathname is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd (rather than relative to the current working directory of the calling process, as is done by stat(2) for a relative pathname).
If pathname is relative and dirfd is the special value AT_FDCWD, then pathname is interpreted relative to the current working directory of the calling process (like stat(2)).
If pathname is absolute, then dirfd is ignored.
flags can either be 0, or include the following flag:
- If pathname is a symbolic link, do not dereference it: instead return information about the link itself, like lstat(2). (By default, fstatat() dereferences symbolic links, like stat(2).)
RETURN VALUEOn success, fstatat() returns 0. On error, -1 is returned and errno is set to indicate the error.
ERRORSThe same errors that occur for stat(2) can also occur for fstatat(). The following additional errors can occur for fstatat():
- dirfd is not a valid file descriptor.
- Invalid flag specified in flags.
- pathname is relative and dirfd is a file descriptor referring to a file other than a directory.
VERSIONSfstatat() was added to Linux in kernel 2.6.16.
CONFORMING TOPOSIX.1-2008. A similar system call exists on Solaris.
NOTESSee openat(2) for an explanation of the need for fstatat().
