53 The access and modification times of the file named by
57 are changed as specified by the argument
64 the access and modification times are set to the current time.
65 The caller must be the owner of the file, have permission to
66 write the file, or be the super-user.
72 it is assumed to point to an array of two timeval structures.
73 The access time is set to the value of the first element, and the
74 modification time is set to the value of the second element.
75 The caller must be the owner of the file or be the super-user.
77 In either case, the inode-change-time of the file is set to the current
83 except in the case where the named file is a symbolic link,
86 changes the access and modification times of the link,
89 changes the times of the file the link references.
99 Search permission is denied for a component of the path prefix;
104 and the effective user ID of the process does not
105 match the owner of the file, and is not the super-user, and write
111 points outside the process's allocated address space.
113 An I/O error occurred while reading or writing the affected inode.
115 Too many symbolic links were encountered in translating the pathname.

117 A component of a pathname exceeded
119 characters, or an entire path name exceeded
123 The named file does not exist.
125 A component of the path prefix is not a directory.
131 and the calling process's effective user ID
132 does not match the owner of the file and is not the super-user.
134 The file system containing the file is mounted read-only.
142 does not refer to a valid descriptor.
145 All of the functions will fail if:
152 and the effective user ID of the process does not
153 match the owner of the file, and is not the super-user, and write
157 points outside the process's allocated address space.
159 An I/O error occurred while reading or writing the affected inode.
165 and the calling process's effective user ID
