XVaCreateNestedList() - allocate a nested variable argument list
typedef void * XVaNestedList
XVaNestedList XVaCreateNestedList (int dummy, ... )
The XVaCreateNestedList(3) function allocates memory and copies its arguments into a single list pointer that can be used as value for arguments requiring a list value. Any entries are copied as specified. Data passed by reference is not copied; the caller must ensure data remains valid for the lifetime of the nested list. The list should be freed using XFree(3) when it is no longer needed.
