definition
use the thread-enabled-api by using the META_HAS_THREAD preprocessor define In a thread-environment (pymqmsgque is build with thread support) every thread has its own runtime. This runtime is created as T)hread-L)ocal-S)torage (TLS) and is available using the MkRt call. Using the MkRt call is an expensive task, because it is a function-call. Multiple usage of MkRt create multiple function-calls and this is expensive. To speed this up, two additional technologies are available: #1 the runtime is saved into the object of an instance at obj->runtime #1 instance->path.to.obj.runtime // this is typesafe #2 the runtime is added as first parameter (called "mkrt") to the callback call #1 example: callback( MQ_SERVICE_CALL_ARGS ) If pymqmsgque was not build with thread support than the API changes #1 the first argument "mkrt" is missing #2 the MkRt is always the fastest access to the runtime. To join the two different styles (with/without thread) into one API the MQ_RT_* style macros are available. The most important one is the MQ_RT_REF. The MQ_RT_REF always return a reference (not a pointer) to the runtime. The access-qualifier for a reference is "." and for a pointer is "->". MQ_RT_REF = reference, &MQ_RT_REF = pointer

Detailed Description

MqRuntimeS - the class known as rt or runtime is main pymqmsgque application environment …

The runtime is automatically created as thread-local-storage at startup, so that each new thread receives a thread-specific runtime. Each instance on this thread has a link to the runtime it was created in:

• MkOBJ_R(instance).runtime

The runtime provide the following features:

• the default-error -> MkErrorC
• the runtime local storage (RLS) for various internal features
• application wide configuration data like debug logfile or silent
