Hmm. If you're getting an errno exception ( as opposed to a
conv) I really don't
think that theres anything you can do about it, as its a
problem with the C standard
lib. What OS/version are you running?
what does the equivalent in C give you.
i.e.
FILE* f = fopen(...,"r");
fseek(f,0,SEEK_END);
printf("%ld",ftell(f));
printf("%d",errno);
I'm currently on windows 7. The code you gave me prints 022. It's
weird because it always tries to convert longs to ints and I
think that is weird because the function uses a c_long.
int fseek(FILE* stream, c_long offset, int whence)
It wont even compile if I try giving it a long
Error: function core.stdc.stdio.fseek (shared(_iobuf)* stream,
int offset, int whence) is not callable using argument types
(shared(_iobuf)*, long, int)
I also tried giving it a c_long, but this line
c_long test = 2147483649;
gives this error for some reason...
Error: cannot implicitly convert expression (2147483649L) of
type long to int
It's like c_longs are not longs at all...
