Hello Neil!

Replying to a message of Neil Heller to Darin McBride:

 DM>> So then you may have a struct like this:

 DM>> struct Database {
 DM>>  HDLL hdll; /* can't remember the exact type ;-> */
 DM>>  error_t (*GetEmployee)(struct EmpRecord* r);
 DM>>  error_t (*SaveEmployee)(struct EmpRecord* r);
 DM>> };

 NH> That brings up another point.  How do you create a function pointer
 NH> that  returns something other than that which was passed-in?  For
 NH> example, if  GetEmployee() above were to return a pointer to double
 NH> and  SaveEmployee() were to return a pointer to a structure of type
 NH> struct  foo?

double* (*GetEmployee)(char const* emp_name);
struct foo* (*SaveEmployee)(struct EmpRecord* r);

Of course, the functions that these could point to would need to change similarly.
