Hi. I don't understand why my csv file is not being found. I'm getting:
"Error opening CSV file for reading: datafile : No such file or directory"

I print out "datafile" before it is used by CsvParser; see attached. The XXX line prints out
"XXX AGT/GAMEEMO/S15/PreprocessedEEGData/csvformat/S15G3AllChannels.csv"

I have checked the that the file can be found just fine:
% ls -l AGT/GAMEEMO/S15/PreprocessedEEGData/csvformat/S15G3AllChannels.csv
-rwx------ 1 lingber lir101 4311933 May 16 11:16 AGT/GAMEEMO/S15/PreprocessedEEGData/csvformat/S15G3AllChannels.csv

I'm using your
"CsvParser/examples/usage_example_with_header.c"
for my use. I have not modified csvparser.[ch] .

Thanks for the software, which I got from sourceforge.net .

Lester
