cdflib.getChecksum - Checksum mode

Syntax

mode = cdflib.getChecksum(cdfId)

Description

mode = cdflib.getChecksum(cdfId) returns the checksum mode of the Common Data Format (CDF) file.

Input Arguments

cdfId

Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.

Output Arguments

mode

Either of the following text strings or its numeric equivalent.

'MD5_CHECKSUM'File uses MD5 checksum.
'NO_CHECKSUM'File does not use a checksum.

To get the numeric equivalent of these text strings, use cdflib.getConstantValue.

Examples

Open the example CDF file, and then get the checksum mode of the file:

cdfid = cdflib.open('example.cdf');

checksummode = cdflib.getChecksum(cdfid)


checksummode =

NO_CHECKSUM

% Clean up
cdflib.close(cdfid);
clear cdfid;

References

This function corresponds to the CDF library C API routine CDFgetChecksum. To use these functions, you must be familiar with the CDF C interface. Read the CDF documentation at the CDF Web site. For copyright information, see the cdfcopyright.txt file.
