Names the procedure that obtains the total number of members in a struct. The call structure for this callback is:

struct_member_count_callback id

where id is the symbol ID of the symbol that was validated using the validate_callback procedure.

Names the procedure that defines an addressing expression that specifies how to access the specified member of a struct. The call structure for this callback is:

struct_member_addressing_callback id index

where id is the symbol ID of the symbol that was validated using the validate_callback procedure and index specifies the zero-based position of the member within the struct.

Names the procedure that obtains the type id of the specified member of a struct. The call structure for this callback is:

struct_member_type_callback id index

where id is the symbol ID of the symbol that was validated using the validate_callback procedure and index specifies the zero-based position of the member within the struct.

Names the procedure that obtains the name of the specified member of a struct. The call structure for this callback is:

struct_member_name_callback id index

where id is the symbol ID of the symbol that was validated using the validate_callback procedure and index specifies the zero-based position of the member within the struct.
