Differentiate between a unix directory and file in C and C++

Question

Given a path, say, /home/shree/path/def, I would want to determine if def is a directory or a file. Is there a way of achieving this in C or C++ code?

Answer 1

Alternatively you can use system() function with in built shell command "test".
system returns the exit status of command last executed

 
 string test1 = "test -e filename" ;
 if(!system(test1))
 printf("filename exists") ;

string test2 = "test -d filename" ;
 if(!system(test2))
  printf("filename is a directory") ;

 string test3 = "test -f filename" ;
 if(!system(test3))
  printf("filename is a normal file") ;

but I am afraid this would work only on linux..
