* CSN_DESCR structure:
*
* type:
* This is the CSN type. All existing types are specified in the section above.
*
* i:
* Depending on the contents of the type parameter, the parameter "i" may have following meaning:
* - specifies the number of bits for the CSN_UINT type
* - the offset for an array size by which the size is incremented
* for the CSN_VAR_ARRAY type
* - the length of each element of an array for the CSN_REC_ARRAY type
* - the number of the elements in an array for the CSN_TYPE_ARRAY type
* - the offset to the variable keeping the number of elements of an array for in the CSN_VAR_TARRAY type
* - the number of different data types in a union for the CSN_UNION, CSN_UNION_LH, and for the CSN_CHOICE types
* - the length in bits of the fixed number defined for the CSN_FIXED type
* - the number of lines to skip in the CSN_DESCR type specified for the CSN_NEXT_EXIST, CSN_NEXT_EXIST_LH,
* CSN_NEXT_EXIST_OR_NULL, and CSN_NEXT_EXIST_OR_NULL_LH types
* - the number of bits in a bitmap for the CSN_BITMAP type
* - the value by which the number of bits in a bitmap has to be incremented or decremented for the
* CSN_VAR_BITMAP, CSN_LEFT_VAR_BMP, and CSN_LEFT_BMP_1 types
* - the offset to param1 for the CSN_CALLBACK type
* - ERRORCODE used by the CSN_ERROR type
*
* descr
* This parameter has different meaning depending on the value of the type parameter:
* - the offset for the CSN_UINT_OFFSET type
* - the number of the elements in an array of the CSN_UINT_ARRAY type
* - the offset to the parameter where the size of the array has to be stored for the CSN_REC_ARRAY type
* - the address of the internal structure, describing the member type (by means of the CSN_DESCR type) in the
* CSN_TYPE_ARRAY, CSN_VAR_TARRAY, and CSN_TYPE types
* - the address of the variable of type CSN_ChoiceElement_t describing all elements in the CSN_CHOICE type union
* - the offset to the variable where the number of bits has to be or is stored for the CSN_VAR_BITMAP,
* CSN_LEFT_VAR_BMP, and CSN_LEFT_BMP_1 types
* - the function number (case number) for the CSN_CALLBACK and CSN_CALLBACK_NO_ARGS types
* - the free text used by the CSN_TRAP_ERROR
*
* offset
* This is an offset to the _MEMBER parameter counting from the beginning of struct
* where the unpacked or packed value shall be stored or fetched. The meaning of the _MEMBER parameter
* varies depending on the type which is specified and so is the meaning of the offset parameter.
* Some types (and corresponding macros) do not have the _MEMBER parameter and then the offset parameter
* is not used or is different from the offset to the _MEMBER.
* - the fixed value for the CSN_FIXED type
* - an offset to the variable UnionType for CSN_UNION and CSN_UNION_LH types
* - an offset to the variable Exist for CSN_NEXT_EXIST and CSN_NEXT_EXIST_LH types
* - an offset to param2 in the CSN_CALLBACK type
*
* sz
* - is the name of the parameter within the descr where their unpacked or packed value shall be stored or fetched.
* This paramater is pointed out by the offset parameter in the same CSN_DESCR variable as the sz.
* - the free text used by the CSN_TRAP_ERROR (the same as parameter "i")
*
* serialize
* - stores the size of _MEMBER type in case of the M_TYPE_ARRAY and M_VAR_TARRAY,
* - the address of the function which is provided by the M_SERIALIZE type.
