missing io.h header file?

missing io.h header file?

[Valery Kobrin]

I have an OpenBSD 3.1 box with gcc included in the OS and I could not
find the io.h file or any other header file, containing access()
function. Is it missing in OpenBSD or does not included in gcc at all?

Thanks,
Valery

Usually GCC comes with no header files that you want to use
directly. Your C library should provide the standard functions. 

I suppose you meant this function: ?
,----
| ACCESS(2)                  System calls                 ACCESS(2)
| 
| NAME
|        access - check user's permissions for a file
| 
| SYNOPSIS
|        #include <unistd.h>
| 
|        int access(const char *pathname, int mode);
`----

This is an extract of the man page on my Linux box - I don't know
where OpenBSD (resp. your C library) declares that function, but try
'man 2 access'.
