Question

I would like to know what semaphores, messageQueues, etc… are active in my vxWorks 6.x system. I have access to this information via the debugger, but I would like access to it from the shell.

Is there a way?

Answer 1

VxWorks 6.x provides a function called classShow() which will list all the objects of a specific class (e.g. semaphores, message queues, tasks, …). The following call will give you a list of objects for a given class:

 classShow(objClassIdGet(classId), 1)   The classId types are:   1  windSemClass,       /* Wind native semaphore */   2  windSemPxClass,     /* POSIX semaphore */   3  windMsgQClass,      /* Wind native message queue */   4  windMqPxClass,      /* POSIX message queue */   5  windRtpClass,       /* real time process */   6  windTaskClass,      /* task */   7  windWdClass,        /* watchdog */   8  windFdClass,        /* file descriptor */   9  windPgPoolClass,    /* page pool */   10 windPgMgrClass,     /* page manager */   11 windGrpClass,       /* group */   12 windVmContextClass, /* virtual memory context */   13 windTrgClass,       /* trigger */   14 windMemPartClass,   /* memory partition */   15 windI2oClass,       /* I2O */   16 windDmsClass,       /* device management system */   17 windSetClass,       /* Set */   18 windIsrClass,       /* ISR object */   19 windTimerClass,     /* Timer services */   20 windSdClass,        /* Shared data region */   21 windPxTraceClass,   /* POSIX trace */
