Detailed Description

Utilities for working with FITS files. These are mostly thin wrappers around cfitsio calls, and their main purpose is to transform functions signatures from void pointers and cfitsio's preprocessor type enums to a more type-safe and convenient interface using overloads and templates.

This was written as part of implementing the afw/table library. Someday the afw/image FITS I/O should be modified to use some of these with the goal of eliminating a lot of code between the two.

#define LSST_FITS_CHECK_STATUS	(		fitsObj,
			...
	)		if ((fitsObj).status != 0) throw LSST_FITS_EXCEPT(lsst::afw::fits::FitsError, fitsObj, __VA_ARGS__)

Throw a FitsError exception if the status of the given Fits object is nonzero.

#define LSST_FITS_EXCEPT	(		type,
			fitsObj,
			...
	)		type(LSST_EXCEPT_HERE, lsst::afw::fits::makeErrorMessage((fitsObj).fptr, (fitsObj).status, __VA_ARGS__))

A FITS-related replacement for LSST_EXCEPT that takes an additional Fits object and uses makeErrorMessage(fitsObj.fptr, fitsObj.status, ...) to construct the message.
