fstatat(2) - Linux man page
Name
fstatat - get file status relative to a directory file descriptorSynopsis
#include <sys/stat.h> int fstatat(int dirfd, const char *path, struct stat *int " flags );
Description
If the pathname given in path 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 the pathname given in path is relative and dirfd is the special value AT_FDCWD, then path is interpreted relative to the current working directory of the calling process (like stat(2)).
If the pathname given in path is absolute, then dirfd is ignored.
flags can either be 0, or include the following flag:
- AT_SYMLINK_NOFOLLOW
- If path 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 Value
On success, fstatat() returns 0. On error, -1 is returned and errno is set to indicate the error.Errors
The same errors that occur for stat(2) can also occur for fstatat(). The following additional errors can occur for fstatat():- EBADF
- dirfd is not a valid file descriptor.
- EINVAL
- Invalid flag specified in flags.
- ENOTDIR
- path is a relative path and dirfd is a file descriptor referring to a file other than a directory.
