Re: [Help-gsl] error handling for GSL

Hi Andrew,

Usually.  The error handling tends to be very complete.  "Graceful" is
probably in the eye of the beholder.

It may just "pass it on" which I say because of a GSL_ERROR_SELECT_2
macro appearance in the relevant source:
http://bzr.savannah.gnu.org/lh/gsl/trunk/annotate/head:/specfunc/bessel_j.c#L247

Grepping through the source code tends to be the best way to make
determinations about whether the error handling is sufficient for your
application's needs.
