Member Data Documentation

◆ argvFix

bool libmqmsgque::MqCtxTypeS::argvFix

add first argument in MkBufferListC argument to MqLinkCreate and MqLinkCreateChild

On C, the startup arguments are available as argc and argv arguments of the main procedure. The first argument (argv[0]) has the executable name. Other programming languages like TCL or CSharp does NOT provide the executable name as first argument of the main argv. If argsFix is set to true this will be fixed. Default is false.

◆ callbackMF

MkMarkF libmqmsgque::MqCtxTypeS::callbackMF

Mark the callback-data-pointer.

Definition at line 3746 of file LibMqMsgque_mq.h.

◆ Child

struct MqLinkSetupS libmqmsgque::MqCtxTypeS::Child

setup/cleanup a CHILD object

Attention

Always call this functions using MqLinkCreate and MqLinkDelete.
A child is a parent with libmqmsgque::MqConfigS::parent != NULL.

Definition at line 3722 of file LibMqMsgque_mq.h.

◆ dataMF

MkMarkF libmqmsgque::MqCtxTypeS::dataMF

Mark the data-pointer.

Definition at line 3743 of file LibMqMsgque_mq.h.

◆ fChildAfterFork

MqSetupF libmqmsgque::MqCtxTypeS::fChildAfterFork

cleanup a child fork-process after a new fork-process is created by ccmqmsgque

Definition at line 3710 of file LibMqMsgque_mq.h.

◆ fDecrSelf

MqRefCountF libmqmsgque::MqCtxTypeS::fDecrSelf

decrement the libmqmsgque::MqContextS::obj->self reference counting

"Embedding" ccmqmsgque into an other language create TWO views on the same ctx … an other-language-view and an c-api-view. The libmqmsgque::MqContextS::obj->self is the connection c-api -> other-lng and the other-lng has something equal. Usually the other-lng using libmqmsgque::MqContextS->MkObjectS::refCount++ and libmqmsgque::MqContextS->MkObjectS::refCount– to bind the c-api-view to the other-language-view. For the special purpose of "embedding" a slave into a master*… as example… the *slave is entirely controlled by the master and the libmqmsgque::MqContextS::obj->self have to be protected*… this protection is done with *other-lng-refCount-protection

Definition at line 3701 of file LibMqMsgque_mq.h.

◆ fHelp

MqHelpF libmqmsgque::MqCtxTypeS::fHelp

Create a link to the calling tool help function.

type	default	option	application	context
POINTER	NULL	NO	server/client	parent

As a service to the programmer the ccmqmsgque startup code in MqLinkCreate checks for the both options -h and --help to provide a tool-specific help-page and exit.

Definition at line 3756 of file LibMqMsgque_mq.h.

◆ fIncrSelf

MqRefCountF libmqmsgque::MqCtxTypeS::fIncrSelf

increment the libmqmsgque::MqContextS::obj->self reference counting

"Embedding" ccmqmsgque into an other language create TWO views on the same ctx … an other-language-view and an c-api-view. The libmqmsgque::MqContextS::obj->self is the connection c-api -> other-lng and the other-lng has something equal.

◆ fParentAfterFork

MqSetupF libmqmsgque::MqCtxTypeS::fParentAfterFork

cleanup a parent fork-process after a new fork-process is created by ccmqmsgque

Definition at line 3707 of file LibMqMsgque_mq.h.

◆ fParentBeforeFork

MqSetupF libmqmsgque::MqCtxTypeS::fParentBeforeFork

setup and initialize a fork-process before a new fork-process is created by ccmqmsgque

Definition at line 3704 of file LibMqMsgque_mq.h.

◆ fProcessExit

MqExitF libmqmsgque::MqCtxTypeS::fProcessExit

exit/cleanup a process

Definition at line 3713 of file LibMqMsgque_mq.h.

◆ fSpawnInit

MqSetupF libmqmsgque::MqCtxTypeS::fSpawnInit

setup and initialize a spawn-process before a new spawn-process is created by ccmqmsgque

Definition at line 3762 of file LibMqMsgque_mq.h.

◆ fThreadExit

MqExitF libmqmsgque::MqCtxTypeS::fThreadExit

exit/cleanup a thread

Definition at line 3716 of file LibMqMsgque_mq.h.

◆ fThreadInit

MqSetupF libmqmsgque::MqCtxTypeS::fThreadInit

setup and initialize a thread before a new thread is created by ccmqmsgque

Definition at line 3759 of file LibMqMsgque_mq.h.

◆ Idle

struct MqCallbackS libmqmsgque::MqCtxTypeS::Idle

Create a link to the calling tool idle-event-handling …

The Idle-Function is used to process tasks in the background to give the tool-user the feeling of a non-blocking application. For example Tcl using the event-handling to update the Tk user-interface while the application is waiting for data. The Idle-Function is called on idle-time and is designed for a very short function execution time. Do only one action per function call. This function will be called with a ~10000 usec interval to guarantee a parallel like execution.

Attention: The libmqmsgque::MqCallbackS::data will not be freed or protected against garbage collection, -> only use libmqmsgque::MqCallbackS::fCall

Definition at line 3740 of file LibMqMsgque_mq.h.

◆ ignoreDisasterSetup

bool libmqmsgque::MqCtxTypeS::ignoreDisasterSetup

do not setup the disaster-handler at startup.

The disaster-handler bind the function MkDisasterSignal to the signal SIGSEGV and is used to print the stack-trace and additional MqContextC data to MkRuntimeS::logFILE on crash.

The problem is, if a target-application (language) needs SIGSEGV, this function can be deactivated with ignoreDisasterSetup = true.

bool libmqmsgque::MqCtxTypeS::ignoreFork

do not allow the usage of fork

Definition at line 3691 of file LibMqMsgque_mq.h.

◆ ignoreSpawn

bool libmqmsgque::MqCtxTypeS::ignoreSpawn

do not allow the usage of spawn

Definition at line 3688 of file LibMqMsgque_mq.h.

bool libmqmsgque::MqCtxTypeS::ignoreThread

do not allow the usage of threads

Definition at line 3685 of file LibMqMsgque_mq.h.

◆ obj

Definition at line 3667 of file LibMqMsgque_mq.h.

◆ Parent

struct MqLinkSetupS libmqmsgque::MqCtxTypeS::Parent

setup/cleanup a PARENT object

Attention: always call this functions using MqLinkCreate and MqLinkDelete

Definition at line 3726 of file LibMqMsgque_mq.h.

◆ [union]
