NAME

       Math::GSL::Errno - Error Handling

SYNOPSIS

           use Math::GSL::Errno qw/:all/;
           gsl_set_error_handler_off();

           print gsl_strerror($GSL_EDOM) . "\n";

STATUS CODES

       •   $GSL_SUCCESS

           Success

       •   $GSL_FAILURE

           General Failure

       •   $GSL_CONTINUE

           Iteration has not converged

       •   $GSL_EDOM

           Domain error; used by mathematical functions when an argument value does not fall into
           the domain over which the function is defined (like EDOM in the C library)

       •   $GSL_ERANGE

           Range error; used by mathematical functions when the result value is not representable
           because of overflow or underflow (like ERANGE in the C library)

       •   $GSL_EFAULT

           Invalid Pointer

       •   $GSL_EINVAL

           Invalid argument. This is used to indicate various kinds of problems with passing the
           wrong argument to a library function (like EINVAL in the C library).Invalid argument.
           This is used to indicate various kinds of problems with passing the wrong argument to
           a library function (like EINVAL in the C library).

       •   $GSL_EFAILED

           Generic Failure

       •   $GSL_EFACTOR

           Factorization Failed

       •   $GSL_ESANITY

           Sanity Check Failed

       •   $GSL_ENOMEM

           No memory available. The system cannot allocate more virtual memory because its
           capacity is full (like ENOMEM in the C library). This error is reported when a GSL
           routine encounters problems when trying to allocate memory with malloc.

       •   $GSL_EBADFUNC

           Problem with user-supplied function

           Failed to reach the specified tolerance

       •   $GSL_EUNDRFLW

           Underflow

       •   $GSL_EOVRFLW

           Overflow

           Integral/Series is divergent

       •   $GSL_EUNSUP

           Not supported by hardware

       •   $GSL_EUNIMPL

           Not implemented

FUNCTIONS

       •   gsl_error

       •   gsl_stream_printf

       •   gsl_strerror($gsl_errno) - This function returns a pointer to a string describing the
           error code gsl_errno. For example, print ("error: gsl_strerror ($status)\n"); would
           print an error message like error: output range error for a status value of
           GSL_ERANGE.

       •   gsl_set_error_handler

       •   gsl_set_error_handler_off() - This function turns off the error handler by defining an
           error handler which does nothing. This will cause the program to continue after any
           error, so the return values from any library routines must be checked. This is the
           recommended behavior for production programs. The previous handler is returned (so
           that you can restore it later).

       •   gsl_set_stream_handler
