cdflib.getVarMaxWrittenRecNum
Maximum written record number for variable
Syntax
maxrec = cdflib.getVarMaxwrittenRecNum(cdfId,varNum)
Description
returns the record number of the maximum record written for a variable in a
Common Data Format (CDF) file. maxrec
= cdflib.getVarMaxwrittenRecNum(cdfId
,varNum
)
cdfId
identifies the CDF file. varNum
is
a numeric value that identifies the variable. Variable numbers and
record numbers are zero-based.
Examples
Open the example CDF, and then determine the maximum number of records written to a variable:
cdfId = cdflib.open("example.cdf"); % Determine the number records written to variable numRecs = cdflib.getVarNumRecsWritten(cdfId,0)
numRecs = 24
% Determine the maximum record number of the records written
maxRecNum = cdflib.getVarMaxWrittenRecNum(cdfId,0)
maxRecNum = 23
% Clean up cdflib.close(cdfId) clear cdfId
Tips
This function corresponds to the CDF library C API routine
CDFgetzVarMaxWrittenRecNum
.To use this function, you must be familiar with the CDF C interface. You can access the CDF documentation at the CDF website.
