146 The file system containing the file pointed at by

150 The link count of the file pointed at by
156 prefix denies search permission.
158 The requested link requires writing in a directory with a mode

191 The directory in which the entry for the new link is being placed
192 cannot be extended because there is no space left on the file

195 The directory in which the entry for the new link
196 is being placed cannot be extended because the

209 is outside the process's allocated address space.
216 In addition to the errors returned by the
220 system call may fail if:

235 argument is not valid.
241 argument is not an absolute path and
