Revision History 44 *! ================ 45 *! 14-Mar-2002 map Set *pBuffer to null before returning error status in 46 *! DSPNode_AllocMsgBuf. 47 *! 01-Oct-2001 rr CMM error codes are converted to DSP_STATUS in 48 *! DSPNode_Allocate. 49 *! 11-Sep-2001 ag Zero-copy message support. 50 *! 08-Jun-2001 jeh Fixed priority range check in DSPNode_ChangePriority. 51 *! 23-Apr-2001 jeh Added pStatus parameter to DSPNode_Terminate. 52 *! 06-Feb-2001 kc: Added check for alignment value in DSPNode_AllocMsgBuf 53 *! 08-Dec-2000 ag Added alignment to DSPNode_AllocMsgBuf(). 54 *! 05-Dec-2000 ag Added SM support to DSPNode_[Alloc][Free]MsgBuf(). 55 *! 09-Nov-2000 rr: Code cleaned up. Use of IsValidEvent/Mask Macros. 56 *! 27-Oct-2000 jeh Updated to version 0.9 of API spec. 57 *! 07-Sep-2000 jeh Changed type HANDLE in DSPNode_RegisterNotify to 58 *! DSP_HNOTIFICATION. Added DSP_STRMATTR param to 59 *! DSPNode_Connect. 60 *! 04-Aug-2000 rr: Name changed to DSPNode.c 61 *! 27-Jul-2000 rr: Types updated to ver 0.8 API. 62 *! 18-Jul-2000 rr: Node calls into the Class driver. 63 *! Only parameters are validated here. 64 *! 17-May-2000 rr: DSPNode_Connect checks for GHPPNODE. 65 *! 15-May-2000 gp: Made input args to DSPNode_Allocate() CONST. 66 *! Return DSP_ENOTIMPL from DSPNode_ChangePriority(). 67 *! 02-May-2000 rr: Reg functions use SERVICES. 68 *! 12-Apr-2000 ww: Created based on DirectDSP API specification, Version 0.6. 69 * 70 */ 71 72/* ----------------------------------- Host OS */ 73#include <host_os.h> 74#include <stdlib.h> 75#include <malloc.h> 76 77/* ----------------------------------- DSP/BIOS Bridge */ 78#include <dbdefs.h> 79#include <errbase.h> 80 81/* ----------------------------------- Trace & Debug */ 82#include <dbg.h> 83#include <dbg_zones.h> 84 85/* ----------------------------------- Resource Manager */ 86#include <memry.h> 87 88/* ----------------------------------- Others */ 89#include <dsptrap.h> 90 91/* ----------------------------------- This */ 92#include "_dbdebug.h" 93#include "_dbpriv.h" 94 95#include <DSPNode.h> 96 97#ifdef DEBUG_BRIDGE_PERF 98#include <perfutils.h> 99#endif 100 101/* ----------------------------------- Globals */ 102extern int hMediaFile;
