Regular API function

simCallScriptFunctionEx (remote API equivalent: simxCallScriptFunction)

Description Calls a script function (from a plugin, the main client application, or from another script). This represents a callback inside of a script. Call this only:
a) from the main thread, or:
b) from a thread that originated from a threaded child script. In that case, you cannot call non-threaded child scripts.
When calling simulation scripts, then simulation must be running. See also sim.executeScriptString and sim.setScriptVariable.

Data exchange between a plugin and a script happens via a stack. Reading and writing arguments from/to the stack gives you a maximum of flexibility, and you wil be able to exchange also complex data structures. But it can also be tedious and error prone. Use instead the helper classes located in programming/common/stack and programming/include/stack: they will greatly simplify the task. Have a look at the example plugins v_repExtSkeletonPlugin and v_repExtSkeletonPluginNG.
C synopsis simInt simCallScriptFunctionEx(simInt scriptHandleOrType,const simChar* functionNameAtScriptName,simInt stackId)
C parameters
scriptHandleOrType: the handle of the script, otherwise the type of the script:
sim_scripttype_mainscript (0): the main script will be called.
sim_scripttype_childscript (1): a child script will be called. In that case, functionNameAtScriptName should also contain the name of the object associated with the script.
sim_scripttype_customizationscript (6): a customization script will be called. In that case, functionNameAtScriptName should also contain the name of the object associated with the script.
functionNameAtScriptName: the name of the Lua function to call in the specified script. If scriptHandleOrType is sim_scripttype_childscript, or sim_scripttype_customizationscript, then functionNameAtScriptName should also contain the name of the object associated with the script: "functionName@objectName".
stackId: a stack handle. The stack represents the function's in/out values. See also the available stack functions.
