Hi there people,
A quick question, I am used to using c programming on a amdahl, but
also started working on msdos Turbo-c 1.5. I am having
problems with reading and writing to a file. I am using a structure of about
8 to 10 doubles in it.
struct empdata {
double wages;
double tariff;
..
..
double netwages;
} EmpData;
When I am writing and reading to a file, a lot of the time I get an fread error
19 invalid argument. I can figure it out. Does this have something to do
with using ptr=fopen("DATA","r+b"); . I have never seen "r+b" before, but maybe
that is the problem. could somebody explain this r+b and tell me if this is
my problem.
Please respond to the above newsgroups or ihlpb!eotto, don't respond to the
default address PLEASE.
Thanks guys .
