What I was thinking was to have a POSIX call, in which the function maps 
as much as it can into the stat structure and an Apple only call which 
returns all the information.  The example would resemble the DIO calls 
in the Atari namespace.

For example:
  int fstat(int fd, struct stat *buf);  /* standard POSIX call */
  int dio_get_file_info(int fd, struct a2_stat *buf);  /* apple namespace */

I am looking for a status of what's been done and if we're even 
compatible.  Oliver might be working on ProDOS 16 implementation where 
I'm working in ProDOS 8.

"... my own ideas ob how things should be done..."

I'm not too sure what you mean by this.  Functionally ? Internal 
structure ? Syntax ?

For example: I've coded the Apple libraries to correspond with the POSIX 
calls
 int chdir(const char* path);
 int __fastcall__ close(int fd);
 int creat(const char *name, mode_t mode);
 int flush (int fd);
  ... and so on ...

The hacks in the write and read functions have been worked with so that 
using the STDIO consts work.  Example:
    fwrite(&msg0[0],1,11,stdout);   /* writes to screen - stderr will 
write to screen also */
    f1 = fopen(&filename[0],"w");
    fwrite(&msg1[0],1,6,f1);            /* writes to open file */

Thanks
Jim
