Question C....Search a string for a string


Does anybody know of a function or have a code example that searches a string, for contents of another string? For example, I would like C program to look at file names, and be able to search each "filename/string" for ".exe".

Thanks.

Code:
if (strstr(myfilename, ".exe")!=NULL)
{
    //Is an exe
}
strstr returns a pointer to the place in string1 where string2 was found.

Enjoy!

If you want to make sure that ".exe" are the last 4 characters in the filename, then this approach might be better:

Code:
if(strlen(filename) > 4)
  if(strcmp(filename+strlen(filename)-4, ".exe") == NULL)
  {
    // It's a .exe
  }

Actually...

Since he is doing this for Windows (at least I think he is, why else .exe?), then this would probably be even better:

Code:
if(strlen(filename) > 4)
  if(stricmp(filename+strlen(filename)-4, ".exe") == NULL)
  {
    // It's a .exe
  }
