SWModSearch = define_c_func(swordLib, "SWModule_doSearch", {C_POINTER, C_CHAR,
C_INT, C_INT, C_POINTER, C_POINTER},
C_POINTER)
global function EuSWModSearch(atom mod, sequence searchString, atom searchType,
atom params ,atom

You want to use call_back():

constant EuSWModSearch_cb = call_back( routine_id("EuSWModSearch") )
