What does subfile_fopen do? Sounds like a FILE* variant of subfile_open,
in which case it wouldn't be a system call but a libc function.


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

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.
