Returns an instance of the object which searches the Te\-X tree, using Karl's path-\/searching algorithm (K\-P\-S\-E). 

Note that, although it looks as if you should be able to call this more than once with different parameters, you can't in fact, and if you call it more than once (that's fine and sensible) you get the same instance back each time. In fact, there's no good reason I can think of why you'd {\itshape want} to initialise this in different ways, so this isn't a problem in fact. The door remains open to this changing in future, though. About the only reason for giving non-\/default parameters here is to register a different {\ttfamily program\-\_\-name} for the kpathsea library to use when reporting errors or warnings.


\begin{DoxyParams}{Parameters}
{\em program\-\_\-name} &amp; the name to be used in kpathsea feedback; if zero, this default to the value set by \hyperlink{classKarlPathSearcher_a47c5d967e21e31ab3161a34eb008b183}{set\-Program\-Name}, and if that has not been set, to {\ttfamily \char`\"{}tex\char`\"{}} \\
\hline
{\em basedpi} &amp; the base resolution of the P\-K fonts; if zero, it is taken to be \hyperlink{classPkFont_a4f830aadba0fe1febcef59b1a175cb09}{Pk\-Font.\-dpi\-Base} (a sensible default) \\
\hline
\end{DoxyParams}

Sets the verbosity level. 

As well as setting the intrinsic level of chatter for this class, it controls the amount of chatter from the {\ttfamily libkpathsea} library itself\-: if the {\ttfamily level} is above {\ttfamily debug}, then {\itshape all} kpathsea debugging information is switched on. 
\begin{DoxyParams}{Parameters}
{\em level} &amp; the desired verbosity level \\
\hline
\end{DoxyParams}
\begin{DoxyReturn}{Returns}
the previous verbosity level
