\stmodindex{stat}
|
||
|
|
|
||
|
|
The \code{stat} module defines constants and functions for interpreting the
|
||
|
|
results of \code{os.stat} and \code{os.lstat} (if it exists). For complete
|
||
|
|
details about the \code{stat} and \code{lstat} system calls, consult your
|
||
|
|
local man pages.
|
||
|
|
|
||
|
|
The \code{stat} module defines the following functions:
|
||
|
|
|
||
|
|
\renewcommand{\indexsubitem}{(in module stat)}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISDIR}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a directory file.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISCHR}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a character special device.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISREG}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a regular file.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISFIFO}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a FIFO.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISLNK}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a symbolic link.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{S_ISSOCK}{mode}
|
||
|
|
Return non-zero if the mode was gotten from a socket.
|
||
|
|
\end{funcdesc}
|
||
