Ever wanted to know what a particular error code means when you are left without the informative error message text?
Use the following small C program to find out:
#include <stdio.h>
#include <errno.h>
int main (int argc, char* argv[])
{
if (argc < 2)
{
printf("Supply the errno on the cmdline.\n");
return 0;
}
errno = atoi(argv[1]);
perror("Message");
return errno;
}
#include <errno.h>
int main (int argc, char* argv[])
{
if (argc < 2)
{
printf("Supply the errno on the cmdline.\n");
return 0;
}
errno = atoi(argv[1]);
perror("Message");
return errno;
}
This can be considered a very simple equivalent to the Windows 'Visual C++ Error Lookup' program (but I've also included here to test out Geshi syntax highlighting).
