It would be useful to include the name of the file you are attempting
to open, although it does make the code more complicated- you have to
create the string you want to output in a temporary buffer:
static const char filename[] = "nonexistent.file";
if (!(fp = fopen(filename, "r")))
{
char tmp[100];
sprintf(tmp, "Unable to open file \"%s\"", filename);
perror(tmp);
resulting in:
Unable to open file "nonexistent.file": No such file or directory
