Single package operations

This category involves single package operations. The virtual methods supplied are:

• $\texttt{string checkstatus(void *}$pkgPtr $\texttt{)}$: it retrieves the package installation status;
• $\texttt{string getRealPath(void *}$pkgPtr $\texttt{)}$: looking at section and priority settings, it builds the virtual pathname of the package identified by pkgPtr. If a valid value is set, this function searches for the category name the package belongs to, so that it can build the pathname to return. In this way the package virtual directory entry is automagically placed;
• $\texttt{int getInfo(void *}$pkgPtr, $\texttt{string \&}$buffer $\texttt{)}$: this methods gets the package information and returns it in a buffer;
• $\texttt{int getDepends(void *}$pkgPtr, $\texttt{string \&}$buffer $\texttt{)}$ and
  $\texttt{int getRDepends(void *}$pkgPtr, $\texttt{string \&}$buffer $\texttt{)}$: they return respectively the dependencies and the reverse dependencies of the package identified by pkgPtr ;
• $\texttt{int getOwnedFiles(string }$pkg_name, $\texttt{string \&}$buffer $\texttt{)}$: it fills the buffer with pathnames of the files owned by package.
