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 Values

S_OK indicates 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 result in unexpected termination of the application.
