How to check for existance of files

[shiv_tech_quest]

Hi Folks,

How do I check for the existance of files with a common pattern in any specific directory.

For eg:
list of filenames

x_tmp_y;
y-tmp_z;
....
....

The patter I will check for files that have "_tmp_" as part of their filename.

Any help in this direction will be greatly appreciated

Huh? Do you know the pattern before hand? Is the pattern being given to you by someone? Are you trying to figure out if files in a directory have a pattern to them? What are you doing?

I have a directory in which there could be huge list of files. But only few files in that directory would have a specific text "_tmp_" as part of their filename.

I have written a block of code that will move all files that have that character as part of the filename to another directory.

I am using

if(system("mv *_tmp_* /tmp") != 0)
{
    // print error message
}

The situation is that if no files exist, that would fail. So I would like to know whether any file exists at all with that string as part of the file name.

If it were a single file, I could have happily made use of access() but well this is a different situation all to gether.

Hi Guys,

I am still waiting to see a solution.. in here...

You can use the following functions:
FindFirstFile()
FindNextFile()
FindClose()

I think these are Windows functions, but i don't know of any other...

Thanks for those functions.... but I am working on Sun Solaris... and no such functions exist.....

So I am still at SQUARE ONE

FILE *fp;
system("ls | grep _tmp_ > outfile");
fp = fopen("outfile","r");

etc.
