Error Handling Routines

cgio_error_message

C Signature

int cgio_error_message(char *error_msg)

Fortran Signature

subroutine  cgio_error_message_f(error_msg, ier)

Parameters

error_msg

OUT: Error message from CGIO or the underlying database manager.

Returns

ier - Error status

Modes

- - -

Description

Gets the error message for the last error encountered, and returns it in error_msg, Maximum length of the error message is CGIO_MAX_ERROR_LENGTH (80). In C, error_msg should be dimensioned at least 81 in the calling routine to allow for the terminating '0'. The function returns the error code corresponding to the error message.

cgio_error_code

C Signature

void cgio_error_code(int *errcode, int *file_type)

Fortran Signature

subroutine  cgio_error_code_f(errcode, file_type)

Parameters

errcode	OUT: The last error code from CGIO or the underlying database manager.
file_type	OUT: Where the last error was encountered. CGIO_FILE_NONE for an error coming from CGIO, else the type of database.

Modes

- - -

Description

Returns the last error code in errcode and where is was generated in file_type. If the error code is < 0, then the error is from the CGIO library, and file_type will be CGIO_FILE_NONE, otherwise file_type will be the type of database.

cgio_error_exit

C Signature

void cgio_error_exit(const char *msg)

Fortran Signature

subroutine  cgio_error_exit_f(msg)

Parameters

msg	IN: An additional message to print, which prefixes the error message before exiting. This may be NULL or an empty string, in which case it is not printed.

Modes

- - -

Description

Prints msg and any error message to stderr and exits. The exit code will be abort_flag if it is set, else −1. If msg is NULL or an empty string, then it is not printed.

cgio_error_abort

C Signature

void cgio_error_abort(int abort_flag)

Fortran Signature

subroutine  cgio_error_abort_f(abort_flag)

Parameters

abort_flag

IN: Abort on error flag.

Modes

- - -

Description

Sets the flag to abort (exit) when an error is encountered. If abort_flag is non-zero, then an error in the CGIO routines or database managers will cause cgio_error_exit() to be called. The exceptions are cgio_is_supported(), cgio_check_file(), and cgio_is_link(). These routines will not cause an abort on an error.

Note

1

The user is trying to create a new file and give it a name. The system has responded that the name has already been used.

2

The user wants to open an existing file that supposedly has the given name. The system has responded that no file by that name exists.

3

When ADF wakes up, it tries to figure out what data format the machine it is running on uses (e.g., IEEE big endian, IEEE little endian, Cray). If it doesn’t recognize the format, it can’t convert files created on other platforms to the current one, so it issues this error message and punts.
