MSDN

The following code example shows you a minimal use of FindFirstFile.

#include <windows.h> #include <stdio.h> int main(int argc, char *argv[]) {   WIN32_FIND_DATA FindFileData;   HANDLE hFind;   printf ("Target file is %s.\n", argv[1]);   hFind = FindFirstFile(argv[1], &FindFileData);   if (hFind == INVALID_HANDLE_VALUE)   {     printf ("Invalid File Handle. GetLastError reports %d\n",             GetLastError ());     return (0);   }   else   {     printf ("The first file found is %s\n",             FindFileData.cFileName);     FindClose(hFind);     return (1);   } }
