can i pass a structure in the command line parameter of CreateProcess

I want to know if i can pass a complete structure in the commandline
argument of CreateProcess function.At present Iam able to pass the
structure but only the 1st member of the structure is being read at
the child process.So if some one can send me a simple code for reading
the complete structure at the child process passed from the parent in
the command line parameter of CreateProcess function.
