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

One of the following character vectors or its numeric equivalent.

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

To get the numeric equivalent of the constants specified by these character vectors, 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
