Re: Misc C question

I think we have a mistake here.
It seems that what was asked is whether the file being opened has or not 
  a read permission.
Yes, your aplication will compile normally and if you don't have read 
permissions on the file, fopen() will return NULL and set errno. By the 
way, checking errno is a good way of tracking down errors, try it.

The man page says (both Linux and Solaris):
"Upon  successful  completion  fopen,  fdopen  and  freopen
return a FILE pointer.  Otherwise, NULL  is  returned  and
the global variable errno is set to indicate the error."

see ya
