GetPropInfos

Return a list of published properties.

Declaration

Source position: typinfo.pp line 198

Description

GetPropInfos stores pointers to the property information of all published properties of a class with class info TypeInfo in the list pointed to by Proplist. The PropList pointer must point to a memory location that contains enough space to hold all properties of the class and its parent classes.

Errors

No checks are done to see whether PropList points to a memory area that is big enough to hold all pointers.
