Usually the best approach is to try to open the file, and handle the
error if the attempt fails. Providing information about *why* it
failed can be useful, but it isn't absolutely necessary, and it can't
be done portably.

Isn't this portable?

... proper #include's, etc. implied ...

errno=0;
f = fopen(filename,mode);
if ( f == NULL )
{
if ( errno != 0 )
perror(filename);
else
fprintf(stderr,"fopen() of %s failed.\n",filename);
exit(EXIT_FAILURE);
}
