Capability Operations

Capabilities are written in a convenient ASCII format, also used by the Amoeba utilities c2a(U) and a2c(U). For example: 

>>> amoeba.name_lookup('/profile/cap')
aa:1c:95:52:6a:fa/14(ff)/8e:ba:5b:8:11:1a
>>>

The following methods are defined for capability objects.


\begin{funcdesc}{dir_list}{} Returns a list of the names of the entries in an Amoeba directory. \end{funcdesc}


\begin{funcdesc}{b_read}{offset\, maxsize} Reads (at most) \var{maxsize} bytes f... ...data is returned as a string. EOF is reported as an empty string. \end{funcdesc}


\begin{funcdesc}{b_size}{} Returns the size of a bullet file. \end{funcdesc}


\begin{funcdesc}{dir_append}{} \funcline{dir_delete}{}\ \funcline{dir_lookup}{}... ...lity is ignored, since this is the defined semantics for Amoeba.) \end{funcdesc}


\begin{funcdesc}{std_info}{} Returns the standard info string of the object. \end{funcdesc}


\begin{funcdesc}{tod_gettime}{} Returns the time (in seconds since the Epoch, in UCT, as for POSIX) from a time server. \end{funcdesc}


\begin{funcdesc}{tod_settime}{t} Sets the time kept by a time server. \end{funcdesc}
