This function converts a class identifier into a string of printable characters. Different class identifiers always convert to different strings.
Syntax
WINOLEAPI StringFromCLSID(
REFCLSID rclsid,
LPOLESTR* ppsz
);
Parameters
- rclsid
[in] Class identifier to be converted.
- ppsz
[out] Address of LPOLESTR pointer variable that receives a pointer to the resulting null-terminated string.
Return Value
S_OK indicates that the class identifier was successfully converted and returned. The standard return value E_OUTOFMEMORY is also supported.
Remarks
The StringFromCLSID function calls the StringFromGUID2 function to convert a globally unique identifier (GUID) into a string of printable characters.
The caller is responsible for freeing the memory allocated for the string by calling CoTaskMemFree.
Passing into this function any invalid and, under some circumstances, NULL pointers results in unexpected termination of the application.
