/**************************************************
* examples of an hand written interface
* Shows how to pass a Scilab list as argument
* and return a list (same for tlist and mlist)
*
* GetRhsVar(n,'l',&m,&n,&l) is used to check that
* argument n is a list and m can be used to check the length
* of the list
* Then the arguments of the list can be accessed through
* GetListRhsVar and GetListRhsCVar with a limitation:
* "l" cannot be used as second argument of GetListRhsVar
* Note: also that PutLhsVar is not able to perform back
* conversion for list arguments. Thus, if a conversion was performed
* in the GetListRhsVar process (which is the case with 'i','c','r','z'
* arguments) the list argument must not be returned.
* For example:
* GetRhsVar(1,'l',...)
* GetListRhsVar(1,1,'c',...)
* LhsVar(1)=1
* will return wrong data
*
* CreateVarFrom or CreateListVarFrom mus be used to provide
* correct code (see below)
*
