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

Open example CDF, and then get information about entries associated with an attribute in the file:
cdfid = cdflib.open('example.cdf');
% The fourth attribute is of variable scope.
attrscope = cdflib.getAttrScope(cdfid,3)
attrscope =
VARIABLE_SCOPE
% Get information about the first entry for this attribute
[dtype numel] = cdflib.inquireAttrEntry(cdfid,3,0)
dtype =
cdf_char
numel =
10
% Clean up
cdflib.close(cdfid);
