Hello,

you can get this information using getuid() combined with getpwuid(). See an example below (error handling etc. have been omitted...)

Code:
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <pwd.h>

int
main()
{
   struct passwd *pwd;

   if ( (pwd=getpwuid(getuid())) != NULL )
   {
      printf("Home Dir of user running the program: %s\n", pwd->pw_dir);
   }

   return 0;
}

HTH,
Loïc
