error handlling in C

[broli]

Is it generally a good idea to use perror() function to handle all the
error situations ?

For eg in one of my modules I have used it extensively.

int reader()
{
FILE *zeus_file;
............... .....
............... ......

zeus_file = fopen("sphere.z eus", "r");
if(zeus_file == NULL)
{
perror("File open error");
return -1;
}

............... ............... ............... .

}

Perror doesn't handle anything. All it does is print an error message.
Whether that is a good idea depends on who is going to be reading it.
