C on Cygwin using Gcc stat function {Resolved}

[señorbadger]

hello, excuse this work since im not that familiar with C but my university assignment says i must use it for this application.

I have to make a application to copy files with confirm overwrites i seem to have hit an issue

Im compiling this code using the Cygwin VM running on Windows XP compiling with GCC. can anyone see what is wrong with this code ?

#include <stdio.h>
#include <sys/stat.h>
#include <stdlib.h>
#include <string.h>

struct stat src_info;
struct stat dest_info;

int main(int argc, char **argv[])
{
  //make sure we have a valid number of arguments
  if (argc == 3)
  {
     printf("Source: %s\nDestination: %s\n", argv[1], argv[2]);
     if (_stat(argv[1], &src_info)  == -1) { printf("Error with source could not get i-node\n"); exit(0); }
     if (_stat(*argv[2], &dest_info) == -1) { printf("Error with destination could not get i-node\n"); exit(0); }
  }
}

i compile in Cygwin using...

$ gcc -o bin/safecp safecp.c
safecp.c: In function `main':
safecp.c:15: warning: passing arg 1 of `_stat' from incompatible pointer type

thank you for your help sam

Looks like you have a stray '*' before the filename the second time you call _stat. This will result in passing a character instead of a char*, which just could cause that warning.

Good luck!

Edit: in addition, your declaration for main is wrong, which is what is causing the problem in the first place:
try changing "char** argv[]" to "char* argv[]".

thank u, but my lecturer explained about the **argv today since its an array of strings. and he said the 2 stars are needed. will give it a shot

WoW it worked thanks !
ive decided i hate C C# all the way

There are two legal ways of declaring argv: char **argv and char *argv[]. Maybe argv[][] is legal too, but I don't think so.

It's a bit early to hate C, don't you think?

yeah i guess had to do c last year at uni as well, but im so used to C#, java & php everything just takes 200 times longer.

I think all you people that work with C through choice deserve a heck of respect if i had a hat it would come off to a C / C++ developer, me I like cheap, dirty and fast
