This new * version of IPC should be able to interoperate TCA fully. Client * programs can now link to both tca and ipc. * * Revision 2.1.1.1 1999/11/23 19:07:34 reids * Putting IPC Version 2.9.0 under local (CMU) CVS control. * * Revision 1.1 1996/05/09 01:01:56 reids * Moved all the X_IPC files over to the IPC directory. * Fixed problem with sending NULL data. * Added function IPC_setCapacity. * VxWorks m68k version released. * * Revision 1.1 1996/03/03 04:32:29 reids * First release of IPC files. X_IPC code (8.5), modified to support NM-DS1 IPC. * * Revision 1.13 1996/02/06 19:05:10 rich * Changes for VXWORKS pipes. Note: the read and write sockets descriptors * can be different. * * Revision 1.12 1996/01/30 15:04:56 rich * Fixed var array index problem. Index refers to the enclosing structure. * Added ability to force 32 bit enums and changed some #defs to enums to * ease debugging. Fixed initialization problems for central. * * Revision 1.11 1996/01/27 21:54:18 rich * Pre-release of 8.4. * Added recursive named formatters and "BAD" formats. Also incorporated * Iain's windows changes. * * Revision 1.10 1996/01/10 03:16:28 rich * Fixed libx_ipc_lisp.a to work with dbmalloc. Added central commands to * show resource state and to unlock locked resouces. Fixed a bug where * dispatches were not freed when handlers were cleared. Reset errno variable. * * Revision 1.9 1995/05/31 19:36:35 rich * Fixed problem with reply data being freed early from replys. * Initial work on getting the PC version to work. * * Revision 1.8 1995/03/28 01:14:59 rich * - Added ability to log data with direct connections. Also fixed some * problems with global variables. It now uses broadcasts for watching variables. * - Added preliminary memory recovery routines to handle out of memory * conditions. It currently purges items from resource queues. Needs to * be tested. * - If the CENTRALHOST environment variable is not set, try the current * host. * - Fixed a problem with central registered messages that caused the parsed * formatters to be lost. * - Added const declarations where needed to the prototypes in x_ipc.h. * - x_ipcGetConnections: Get the fd_set. Needed for direct connections. * - Added x_ipcExecute and x_ipcExecuteWithConstraints. Can "execute" a goal * or command. * - x_ipcPreloadMessage: Preload the definition of a message from the * central server. * * Revision 1.7 1995/01/18 22:42:33 rich * X_IPC 7.9: Speed improvements. * Use unix sockets for communication on the same machine. * Eliminate copying. * Optimize loop for arrays, especially simple, primitive arrays. * Optimize the buffer size. * * Revision 1.6 1994/05/25 17:32:35 reids * Added utilities to limit the number of pending messages * * Revision 1.5 1994/05/17 23:17:26 rich * Added global variables and associated routines. * Added some error checking. The central connection is now set to -1 * rather than zero to prevent x_ipc messages from being send to stdout. * Now compiles on the sgi machines. Still need to have the endian and * alignment figured out automatically. * * Revision 1.4 1993/12/01 18:04:24 rich * Fixed a problem with the port number being double converted to network * byte order. * Some general cleanup. * * Revision 1.3 1993/08/27 07:16:43 fedor * First Pass at V7 and V6+VXWORKS merge * * Revision 1.2 1993/05/26 23:18:59 rich * Fixed up the comments at the top of the file. * * Revision 1.1.1.1 1993/05/20 05:45:47 rich * Importing x_ipc version 8 * * Revision 7.1 1993/05/20 00:32:06 rich * RTG - initial checkin of Chris Fedor's version 8 of x_ipc * * Revision 1.2 1993/05/19 17:25:36 fedor * Added Logging. * * 26-Aug-90 Christopher Fedor, School of Computer Science, CMU * New implmentation of resources - x_ipc version 5.0. * * 13-Mar-89 Christopher Fedor, School of Computer Science, CMU * created. * * $Revision: 1.1.1.1 $ * $Date: 2004/10/15 14:33:16 $ * $Author: tomkol $ * *****************************************************************************/ #ifndef INCres #define INCres #define NO_PENDING_LIMIT -1 typedef enum { ActiveResource=0, ReservedResource=1, LockedResource=2 #ifdef FORCE_32BIT_ENUM , dummyResourceStatus = 0x7FFFFFFF #endif } RESOURCE_STATUS_TYPE; typedef struct _RESOURCE { int readSd; int writeSd; char *name; int32 capacity; MODULE_PTR module; RESOURCE_STATUS_TYPE status; struct _LIST *pendingList, *attendingList; int32 pendingLimit; LIST_PTR msgLimitList; } RESOURCE_TYPE, *RESOURCE_PTR; #define RESOURCE_SET_STATUS(stat, resource) (resource->status = stat) RESOURCE_PTR resourceCreate(int readSd, int writeSd, const char *name, int32 capacity); void resourceDelete(RESOURCE_PTR resource); int32 resourceSelfQuery(DISPATCH_PTR); int32 resourceAvailableRes(RESOURCE_PTR resource); int32 resourceAvailable(DISPATCH_PTR dispatch); void resourceAttending(DISPATCH_PTR dispatch); void resourceRemoveAttending(DISPATCH_PTR dispatch); void resourceRemovePending(DISPATCH_PTR dispatch); void resourcePending(DISPATCH_PTR dispatch); void resourceProcessPendingRes(RESOURCE_PTR resource); void resourceProcessPending(DISPATCH_PTR dispatch); void resourceInitialize(void); void purgeResoucePending(void); void showResourceStatus(void); void unlockResource(char *name); #endif /* INCres */
