Detailed Description

template<typename X>
class CCfits::FITSUtil::auto_array_ptr< X >

A class that mimics the std:: library auto_ptr class, but works with arrays.

This code was written by Jack Reeves and first appeared C++ Report, March 1996 edition. Although some authors think one shouldn't need such a contrivance, there seems to be a need for it when wrapping C code.

Usage: replace

float* f = new float[200];

with

FITSUtil::auto_array_ptr<float> f(new float[200]);

Then the memory will be managed correctly in the presence of exceptions, and delete will be called automatically for f when leaving scope.
