Subject: | [Discuss-gnuradio] Using "rb" vs. "r" to open gnuradio data files |
Date: | Thu, 20 Mar 2008 11:13:31 -0400 |
I was attempting to use Chuck Swiger's utility at http://www.swigerco.com/gnuradio/raw2num_f.c to read a gnuradio file created by audio_to_file.py but kept getting "Input reached EOF" well before the entire file had been read. I am not a C programmer, but while debugging I noticed that he had used "r" in his fopen command rather than the "rb" used by gr_file_source.cc so I made that change and now the utility works fine. I also noticed an old post from ematlis (http://lists.gnu.org/archive/html/discuss-gnuradio/2007-05/msg00341.htm l) mentioning a similar utility he'd developed and noticed it uses "r" rather than "rb" also. Shouldn't "rb" be used rather than "r" to open gnuradio data files? By the way, I am using MinGW/MSYS with GCC 3.4.5 if that matters. Thanks, Rob
