Win64 Helper Functions

[This is preliminary documentation and subject to change.]

The following inline functions (defined in Basetsd.h) can help you safely convert values from one type to another.

unsigned long HandleToUlong( const void *h )
long HandleToLong( const void *h )
void *LongToHandle( const long h )
unsigned long PtrToUlong( const void *p )
unsigned int PtrToUint( const void *p )
unsigned short PtrToUshort( const void *p )
long PtrToLong( const void *p )
int PtrToInt( const void *p )
short PtrToShort( const void *p )
void * IntToPtr( const int i )
void * UIntToPtr( const unsigned int ui )
void * LongToPtr( const long l )
void * ULongToPtr( const unsigned long ul )

Warning  IntToPtr sign-extends the int value, UIntToPtr zero-extends the unsigned int value, LongToPtr sign-extends the long value, and ULongToPtr zero-extends the unsigned long value.
