[Sandiaportals-devel] about user_ptr

[radhika s. <de...@gm...>]

hi there,
      So I was trying to learn portal 4 and was going through PtlPut which
takes list of arguments. The second argument (local_offset) is the pointer
to the data to be sent ( I am still confused why it has a type ptl_size_t
though) and third argument the length of data.
      My question is what is user_ptr? I have read the sentence for
user_ptr but I am still confused. Can some one please help me understand
this.
