Comment on Tutorial : perror() Function - example program in C By Lakshmi
Nice example. I think this is more idiomatic tho'.


/* Demonstration of error handling with perror() and errno. */

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>

int main(int argc, char** argv)
{
FILE *fp;

if (fp = fopen(argv[1], "r"))
{
printf("File %s opened for reading.\n", argv[1]);
fclose(fp);
}
else
{
perror("You goofed!");
printf("errno = %d.\n", errno);
exit(1);
}
return 0 ;
}
