Description:
The flink() function assigns the pathname, path, to
the file associated with the file descriptor, fd.
Returns:
- 0
- Success.
- -1
- An error occurred; errno
is set.
Errors:
- EACCES
- A component of either path prefix denies search permission, or the
link named by path is in a directory with a mode that denies
write permission.
- EBADF
- The file descriptor fd is invalid.
- EEXIST
- The link named by path already exists.
- ELOOP
- Too many levels of symbolic links or prefixes.
- EMLINK
- The number of links to the file would exceed LINK_MAX.
- ENAMETOOLONG
- The length of the path string exceeds
PATH_MAX, or a pathname component is longer than NAME_MAX.
- ENOENT
- This error code can mean the following:
- A component of either path prefix doesn't exist.
- The path points to an empty string.
- ENOSPC
- The directory that would contain the link can't be extended.
- ENOSYS
- The flink() function isn't implemented for the filesystem specified in
path.
- ENOTDIR
- A component of either path prefix isn't a directory.
- EROFS
- The requested link requires writing in a directory on a read-only filesystem.
- EXDEV
- The link named by path is on a different logical disk.
