    how to search for a file using C?

    hi all,

    i've got a long long program that does deletion in excel file
    but this excel files get it's information from a text file

    i would like to automate things a little here
    wondering if there's any way where i could search for the file in a particular directory?
    cos my current program requires me to manually key in the name of my file that i'm getting my data from

    i'm using C in windows
    thanks
    :)

      Usually searching for a file in the system involves scripting like perl or Shell script and it works very well.
      So you can have a wrapper script to search for the file and pass that as argument to the C Executable

          yeah i know of perl and stuff
          but i've got a script already in mostly C
          dun wanna mess it up which why i'm trying to figure out if in C i can just detect a file automatically using C language so that the program will go to that file and get its data?
          so any ideas?

                      I've use c in linux to search for a file inside a folder. I'm not sure if it applies to windows land or not but if your stuck maybe it's worth your time to see if you have opendir() and readdir() calls available.

                      Here is a page that explains them:
                      readdir
