aCC 3.70 and C I/O functions

[Craig Smith_13]

I have serveral C functions that I would like to use in my C++ program (without having to rewrite them) that contain functions such as access(), open(), read(), write(), etc. It compiles fine, but returns a -1 when using access() or open().
It has no problems with fread...

Any ideas?

Thanks.

As long as you use the appropriate system header file, you should should be able to use stdio or other libc functions in C++.

If access(2) or open(2) return -1, you should be looking at errno to see what's wrong. You can use strerror(3) to decode errno.

Make sure you include .

Thanks for the response, yes I was using perror().

Found problem, changed base directory from old /users user directory to /home in new version and needed to be changed in the old C code.
