2.3 NF90_STRERROR

The function NF90_STRERROR returns a static reference to an error message string corresponding to an integer netCDF error status or to a system error number, presumably returned by a previous call to some other netCDF function. The list of netCDF error status codes is available in the appropriate include file for each language binding.

Usage

      function nf90_strerror(ncerr)
        integer, intent( in) :: ncerr
        character(len = 80)  :: nf90_strerror
NCERR
An error status that might have been returned from a previous call to some netCDF function.

Errors

If you provide an invalid integer error status that does not correspond to any netCDF error message or or to any system error message (as understood by the system strerror function), NF90_STRERROR returns a string indicating that there is no such error status.

Example

Here is an example of a simple error handling function that uses NF90_STRERROR to print the error message corresponding to the netCDF error status returned from any netCDF function call and then exit:

      subroutine handle_err(status)
        integer, intent ( in) :: status
     
        if(status /= nf90_noerr) then
          print *, trim(nf90_strerror(status))
          stop "Stopped"
        end if
      end subroutine handle_err
