1.5 Error Handling
The netCDF library provides the facilities needed to handle errors in
a flexible way. Each netCDF function returns an integer status
value. If the returned status value indicates an error, you may handle
it in any way desired, from printing an associated error message and
exiting to ignoring the error indication and proceeding (not
recommended!). For simplicity, the examples in this guide check the
error status and call a separate function, handle_err(), to handle any
errors. One possible definition of handle_err() can be found within the
documentation of nc_strerror (see nc_strerror).
The nc_strerror function is available to convert a returned integer
error status into an error message string.
Occasionally, low-level I/O errors may occur in a layer below the
netCDF library. For example, if a write operation causes you to exceed
disk quotas or to attempt to write to a device that is no longer
available, you may get an error from a layer below the netCDF library,
but the resulting write error will still be reflected in the returned
status value.
