pPropertyCount
pPropertyCount is a naming convention used in C and C++ code, particularly in Windows API and COM-style interfaces, to denote a pointer to a count of properties. The leading p signals that the object is a pointer, while PropertyCount describes the data being pointed to.

Usage patterns often treat pPropertyCount as an output parameter. A common two-step approach involves first passing
Contexts where pPropertyCount appears include enumerating properties in a property store, retrieving a list of properties
Considerations when using pPropertyCount include ensuring proper memory allocation and deallocation, validating the count, and handling
