/** \addtogroup error NetCDF Error Handling
|
|
|
|
NetCDF functions non-zero status codes on error.
|
|
|
|
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().
|
|
|
|
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.
|
|
|
|
*/
|
|
|
|
/*! Given an error number, return an error message.
|
|
\addtogroup error
|
|
|
|
This function 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 error codes are defined in netcdf.h.
|
|
|
|
\param ncerr1 error number
|
|
|
|
\returns short string containing error message.

|
\section handle_error_example nc_strerror Example
|
|
|
|
Here is an example of a simple error handling function that uses
|
|
nc_strerror to print the error message corresponding to the netCDF
|
|
error status returned from any netCDF function call and then exit:
|
|
|
|
\code
|
|
#include <netcdf.h>
|
|
...
|
|
void handle_error(int status) {
|
|
if (status != NC_NOERR) {
|
|
fprintf(stderr, "%s\n", nc_strerror(status));
|
|
exit(-1);
|
|
}
|
|
}
|
|
\endcode
