simplest file search

Hi
I am looking for a simple program that goes thru the directory tree to find a file. No MFC and other stuff, just plain Win32 development.

Thnx a lot

Under File Management Functions:
FindFirstFile()

Under Path Functions:
PathFindFileName
PathFindOnPath()

Of course, you may have to use these functions recursively (or in a loop) to search subdirectories. Here is a code snippet from a simple find function I created:

Code:

---

/* calling routine */
...
/* call find on some directory */
find("C:\some\directory\to\start\from");
...
...

void find(const char *rootPath)
{
    char searchTerm[strlen(rootPath)+3];
    strcpy(searchTerm, rootPath);
    strcat(searchTerm, "\*");

    WIN32_FIND_DATA fd;
    HANDLE hFind = FindFirstFile(searchTerm, &fd);
    if(hFind == INVALID_HANDLE_VALUE)
        return;
    do
    {
        /* if its a subdirectory, call find again */
        if(fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY &&
          strcmp(fd.cFileName , ".")!=0 && strcmp(fd.cFileName , "..")!=0)
        {
              char subPath[strlen(rootPath) + strlen(fd.cFileName) + 2];
              strcpy(subPath, rootPath);
              strcat(subPath, "\");
              strcat(subPath, fd.cFileName);
              find(subPath);
        }
        else
        {
            /* do some other stuff its a file */
        }
    }
    while(FindNextFile(hFind, &fd));
    FindClose(hFind);
}

You mean like the many examples in the FAQ then :rolleyes:

Thanks.

A small question:
will char searchTerm[strlen(rootPath)+3];
compile? Should be a constant expression, shouldn't it?

Yes it should be a constant expression.

It's fine if you're using a C99 compliant compiler (which is pretty much any decent compiler).
