91 A component of either pathname exceeded 255 characters,
92 or entire length of either path name exceeded 1023 characters.
94 A component of either path prefix does not exist.
96 The file system containing the file named by
98 does not support links.
100 The link count of the file named by
104 A component of either path prefix denies search permission.
106 The requested link requires writing in a directory with a mode
107 that denies write permission.
109 Too many symbolic links were encountered in translating one of the pathnames.
125 and the file named by
127 are on different file systems.
129 The directory in which the entry for the new link is being placed
130 cannot be extended because there is no space left on the file
131 system containing the directory.
133 The directory in which the entry for the new link
134 is being placed cannot be extended because the
135 user's quota of disk blocks on the file system
136 containing the directory has been exhausted.
138 An I/O error occurred while reading from or writing to
139 the file system to make the directory entry.
141 The requested link requires writing in a directory on a read-only file
144 One of the pathnames specified
145 is outside the process's allocated address space.
