remove command with wildcard characters?

I'm using the following code to remove some files before I write out the new files.

But, I'd like to simply remove all of the .csv files in the directory instead of checking each one individually.

     rc=remove(filename);
     if (rc != 0) {
          exit(rc);
     }

Is there a way to do something like this:  remove("/tmp/*.csv")
And if so, what is the syntax?

Thanks in Advance
John

void RemoveWildCard(char *path)
{
  int found;
  struct ffblk ff;
  int found = FindFirst(path, rta Downloads\\*.*", faAnyFile, &ff);

  while (ff == 0) {
    remove(ff.ff_name);
    ff = FindNext(ff);
  }
  FindClose(ff);
}

Note:
This is for Borland,
Findfirst/findnext is not portable. Checkout your compiler manual.

I forgot some &s

void RemoveWildCard(char *path)
{
 int found;
 struct ffblk ff;
 int found = findFirst(path, rta Downloads\\*.*", faAnyFile, &ff);

 while (found == 0) {
   remove(ff.ff_name);
   ff = findnext(&ff);
 }
 findclose(&ff);
}

Awww ... another mistake :) sorry.
This time I have compiled it at Turbo C++ 3.1

#include <dos.h>
#include <dir.h>
#include <stdio.h>


void RemoveWildCard(char *path)
{
  int found;
  struct ffblk ff;
  found = findfirst(path, &ff, FA_ARCH);
  while (found == 0) {
    remove(ff.ff_name);
    found = findnext(&ff);
  }
  /* findclose(&ff); */
}

Sorry Kocil - didn't see your respones until I posted - duh...  I think that is a Borland-specific function...

For a VisualStudio answer, see the other post

You can also use the system() function to execute an actual command.

if you're using a UNIX-like system, you can do something like

system("rm -f /tmp/*.csv");

here's the man page:
