Question Getting real path to directory

Hi friends,

Need your help. The question is:
1) We have directory '/SomeDirectory/SubDirectory'
2) And have symlink pointing to it like '/AnotherOneDirectory/symlink'
'/AnotherOneDirectory/symlink' -> '/SomeDirectory/SubDirectory'

3) Need to get real path without symlinks knowing only '
/AnotherOneDirectory/symlink'

4) P.S. Using shell commands only.
Something like realpath() call for C.

Thanks, kandrewo.
