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
