56 The access and modification times of the file named by
60 are changed as specified by the argument
67 the access and modification times are set to the current time.
68 The caller must be the owner of the file, have permission to
69 write the file, or be the super-user.
75 it is assumed to point to an array of two timeval structures.
76 The access time is set to the value of the first element, and the
77 modification time is set to the value of the second element.
78 The caller must be the owner of the file or be the super-user.
80 In either case, the inode-change-time of the file is set to the current
86 except in the case where the named file is a symbolic link,
89 changes the access and modification times of the link,
92 changes the times of the file the link references.
102 Search permission is denied for a component of the path prefix;
107 and the effective user ID of the process does not
108 match the owner of the file, and is not the super-user, and write
114 points outside the process's allocated address space.
116 An I/O error occurred while reading or writing the affected inode.
118 Too many symbolic links were encountered in translating the pathname.

120 A component of a pathname exceeded
122 characters, or an entire path name exceeded
126 The named file does not exist.
128 A component of the path prefix is not a directory.
134 and the calling process's effective user ID
135 does not match the owner of the file and is not the super-user.
137 The file system containing the file is mounted read-only.
145 does not refer to a valid descriptor.
148 All of the functions will fail if:
155 and the effective user ID of the process does not
156 match the owner of the file, and is not the super-user, and write
160 points outside the process's allocated address space.
162 An I/O error occurred while reading or writing the affected inode.
168 and the calling process's effective user ID
169 does not match the owner of the file and is not the super-user.
