Functions

AllocAndRegQueryWSZ

Queries a REG_SZ value in the registry, allocates memory for it and returns a buffer containing the value. You have to free this buffer using DllFreeSplMem.

Parameters
hKeyHKEY variable of the key opened with RegOpenKeyExW.
pwszValueNameName of the REG_SZ value to query.
Returns
Pointer to the buffer containing the value or NULL in case of failure.
PWSTR AllocAndRegQueryWSZ (HKEY hKey, PCWSTR pwszValueName)
 
PDEVMODEW DuplicateDevMode (PDEVMODEW pInput)
 
LONG copy_servername_from_name (LPCWSTR name, LPWSTR target)
