57 The access and modification times of the file named by
61 are changed as specified by the argument
68 the access and modification times are set to the current time.
69 The caller must be the owner of the file, have permission to
70 write the file, or be the super-user.
76 it is assumed to point to an array of two timeval structures.
77 The access time is set to the value of the first element, and the
78 modification time is set to the value of the second element.
79 The caller must be the owner of the file or be the super-user.
81 In either case, the inode-change-time of the file is set to the current
87 except in the case where the named file is a symbolic link,
90 changes the access and modification times of the link,
93 changes the times of the file the link references.
103 Search permission is denied for a component of the path prefix;
108 and the effective user ID of the process does not
109 match the owner of the file, and is not the super-user, and write
115 points outside the process's allocated address space.
117 An I/O error occurred while reading or writing the affected inode.
119 Too many symbolic links were encountered in translating the pathname.

121 A component of a pathname exceeded
123 characters, or an entire path name exceeded
127 The named file does not exist.
129 A component of the path prefix is not a directory.
135 and the calling process's effective user ID
136 does not match the owner of the file and is not the super-user.
138 The file system containing the file is mounted read-only.
146 does not refer to a valid descriptor.
149 All of the functions will fail if:
156 and the effective user ID of the process does not
157 match the owner of the file, and is not the super-user, and write
161 points outside the process's allocated address space.
163 An I/O error occurred while reading or writing the affected inode.
169 and the calling process's effective user ID
170 does not match the owner of the file and is not the super-user.
