Get the name of the placement group of a block
const char_T *ssGetPlacementGroup(SimStruct *S)
Use this macro in mdlInitializeSizes to get the name of this block's placement group. A placement group is an advanced feature for S-functions that are either a source block (i.e., a block without input ports) or a sink block (i.e., a block without output ports). All S-functions with the same placement group will be placed adjacent to each other in the sorted list. There is no correlation between different placement groups.
