I want to know if any C libraries are available online that provide functions for performing UNIX commands. For eg. supposing I want to find a file in UNIX, i want to do it thru a C program by calling a function called find() and supplying the same parameters as in find command.

I don't know such a library, but it's simple too

   char *cmd = "/usr/bin/find start_path -name your-pattern -print";
   int   err = 0;
  err = system( cmd );

Or, if you want to process the result:

   FILE *fid = (FILE *)NULL;
   fid = popen(  cmd, "r" );
   while (fscanf( fid, ... ) != EOF) {
       /* your action here */
   }

1. In Linux you have the source for most Unix commands
2. The Standard C library will give basic functionallity. (like findfirst/Findnext etc)
