Functions

See the Overview for header-level documentation.

IOAF_bcopy_WriteCombine

An efficient bcopy from "write combine" memory to regular memory. It is safe to assume that all memory has been copied when the function has completed

extern void IOAF_bcopy_WriteCombine(
   const void *src,
   void *dest,
   unsigned int count );

IOAF_Float32ToNativeInt16

Converts 32-bit floating point to native 16-bit integer

extern void IOAF_Float32ToNativeInt16(
   const Float32 *src,
   SInt16 *dest,
   unsigned int count );

IOAF_Float32ToNativeInt24

Converts 32-bit floating point to native 24-bit integer

extern void IOAF_Float32ToNativeInt24(
   const Float32 *src,
   UInt8 *dest,
   unsigned int count );

IOAF_Float32ToNativeInt32

Converts 32-bit floating point to native 32-bit integer

extern void IOAF_Float32ToNativeInt32(
   const Float32 *src,
   SInt32 *dest,
   unsigned int count );

IOAF_Float32ToSwapInt16

Converts 32-bit floating point to non-native 16-bit integer

extern void IOAF_Float32ToSwapInt16(
   const Float32 *src,
   SInt16 *dest,
   unsigned int count );

IOAF_Float32ToSwapInt24
