Hi,
How to read signed 16-bit binary file?
I opened the file with,
pFile = fopen ("TestRawData","rb");
and I have
fread(&number_bin, 2,1,pFile); to read the data,
but it's not reading the correct value. Does fread only return unsigned values? If so, what command should I use in order to read signed 16-bit?
Thanks! This simple thing has driven me crazy for the passed full day. Please help!

Try to use:
short int number_bin;
If you're still in trouble, let me know - OK?
"fread" returns the number of items read from
the "pFile" stream. If "pFile" points to 10 items, and you decide to read say 4 of these items then the return value is 4.
