Directories in C

[nesha nicole jones]

I was wondering if any one knew if you could read in a variable in C 
and check to see if it is a directory.  If if is I would like to make it a 
directory.  I know how to check to see if something is a file, however,
I could not find anything specifically related to directories.  I know
how to make a directory using shell. but I can't seem to pass the variable
I read using scanf to the system( mkdir ___) command.


Advise would be appreciated.
