Information about entry in attribute with global scope
[datatype,numElements] = cdflib.inquireAttrgEntry(cdfId,attrNum,entryNum)
[datatype,numElements] = cdflib.inquireAttrgEntry(cdfId,attrNum,entryNum)
returns the data type and the number of elements for a global attribute
entry in a Common Data Format (CDF) file.

Open the example CDF, and then get information about entries associated with a global attribute in the file.
cdfid = cdflib.open('example.cdf');
% Any of the first three attributes have global scope.
attrscope = cdflib.getAttrScope(cdfid,0)
attrscope =
GLOBAL_SCOPE
% Get information about the first entry for this attribute
[dtype numel] = cdflib.inquireAttrgEntry(cdfid,0,0)
