int
subfile_open( const char* base_file , const char* base_file , int  
open_flags)

int
subfile_fopen( int base_file , const char* base_file , int open_flags)

So they both return normal int file descriptors, just like open would.  
The difference is how you are getting the basefile. subfile_fopen is  
for a basefile that you already have open and have the fd.
